[002] In the recent times, the Federal Communications Commission (FCC) has assigned millimeter wave frequency bands for Satellite communication systems, including Q (33–50 GHz), V (40 – 75GHz) and W–bands (75 –110GHz) respectively. Especially, it is suggested to distribute a part of the Q - band (37 - 42GHz) to transmissions from satellites, a part of the V –band (42.5 – 51.5GHz) to transmissions to satellites, and another fraction of the V –band (59 – 63GHz) to crosslink transmissions from satellite to satellite.
[003] Citations: US 2012/0094593 A1: Discloses a satellite payload architecture, which provides dual frequency conversion and/or bandwidth aggregation significantly lower mass per unit bandwidth relative to conventional architectures. This disclosure is related to enabling high capacity broadband service from an Earth orbiting satellite, and particularly to payload architecture for such satellite featuring dual frequency conversion and bandwidth aggregation. The payload subsystem has a first and a second frequency converter, a satellite feeder link antenna feed, and a satellite user link antenna feed. The first frequency converter down converts, to a third frequency band, as an aggregated block, signals received at the satellite feeder link antenna feed from the gateway via the feeder link. The third frequency band is substantially lower than both the first and second frequency band. The down converted signals are routed to the second frequency converter for up converting to the second frequency band for transmission over the user link to the user terminals.

This disclosure is related to systems and methods for receiving and processing modulated digital signals. The method explained in this disclosure is it receives the first signal, converting the first signal of the first bandwidth into an intermediate frequency band. Then splitting the converted first signal into N of intermediate signals, each having a bandwidth less than the digital processor bandwidth. Then, down converting each of the N intermediate signals to the second frequency band, processing the down converted plurality of signals with the digital processor to generate N processed signals, up converting each of the N processed signals to the intermediate frequency band, converting the up converted signals to the third frequency band, and transmitting the converted signals.
[005] 2016/US9306792 B2: Describes methods, systems, and apparatuses for down converting a modulated carrier signal to a demodulated baseband signal by sampling a portion of the carrier signal. Briefly, it is operated by receiving a modulated carrier signal and using a control (to control a switch). So that, a portion of the modulated signal can be transferred in the form of charge to a storage capacitor during the ON periods and to discharge the charge in the storage capacitor into a load during the time between the OFF periods. Received RF signal is amplified and down converted twice to get final IF signal by using aliasing technique. Instead of conventional signal processing technique (Nyquist Sampling, as it is known that, when a signal is sampled at less than or equal to twice frequency of the signal, the signal is said to be under sampled or alised) this disclosure follows down conversion of an EM signal by aliasing the EM signal. By taking a carrier and aliasing it at an aliasing rate, then it can down convert the carrier to lower frequencies.

The receiver assembly includes filter, down converter, demodulator, latch, FIFO, and logic circuits. A method of converting 60GHz analogue signal to digital signal also disclosed in this invention. Amplifiers amplify received signal from antennas and then down converted by down converters to an intermediate signal. Then a demodulator adapted to recover data and recover clock signals; a latch for realigning clock signals; a first-in/first-out circuit for organizing and recovering the clock signal; and a logic circuit for correlating known sequences to correct errors in the signal.
[007] WO 2013/089495 Al: Discloses a network node in a wireless network performs a method for enhancing reliability in wireless communication.

[008] Hence, there is a need in the art for a system that allows such frequency bands to be deployed at very low cost to the existing satellite systems. Besides that, the transmitter-receiver and signal processing unit are an important part of the tracking Radar for air surveillance. Thereby, lightweight, cost-effective antenna integrated transmitter-receiver system which can easily be mountable on a top of a portable vehicle has great demand in the industry.
SUMMARY
[009] This summary is provided to introduce concepts of the invention related to an antenna integrated transmitter receiver system, as disclosed herein. This summary is neither intended to identify essential features of the invention as per the present invention nor is it intended for use in determining or limiting the scope of the invention as per the present invention.
[0010] In an embodiment, an apparatus called antenna integrated transmitter (Tx) receiver (Rx) system is more advantageous due to various reasons thereby millimetre wave systems adopts such technique of integration. Such integration method thrusts more power to the antenna at millimetre wave band due to near proximity of transmitters. Receivers also get advantage of lower noise figure due to integrated with receiver antenna in a sophisticated manner. Risk factors of such type of integration are also very high. It requires more sophisticated way of laying out Tx and Rx channels/modules with antenna otherwise it suffers from inter-channel/module interferences which kills the ultimate purpose or goal. Thereby packaging of such millimetre wave modules are a challenge in compact size and must be lightweight as it mounted with antenna array. It has another challenge of producing and distributing second, third and fourth sets of RF signals as well as fifth set of control signals at a time with optimum purity. To make the packaging compact several Tx/Rx channels are housed in a single housing thus the above challenges become even more difficult. Simplicity of this packaging is it receives only one fixed frequency signal 610 (narrowband & <100MHz) and first set of control signals (6201, …, 620N) then produces various intermediate RF signals and up-converts to eighth set of wideband signals then it again receives Ka/Q wideband signals and down converts to tenth set of narrowband signals. This down converted tenth set of N signals are sent to the ground-based system 600 for further processing, wherein, each of N tenth set of signals further down converted and then processed for controls the fire control unit or performs different kind of activities. Major hardware of this whole system contains into control & processing unit and it is communicatively coupled with the antenna integrated transmitter receiver system by cables, waveguide and high-speed data links or by other means. The Apparatus 600 and 200 are not co-located whereas, apparatus 500 is co-located with 300 thus packaging of 300 is more complex as compared to 400. 500 basically produce all the necessary second (506N), third (508N) and fourth (509N) sets of RF signals and fifth set of control signals (507 and distribute each signal into N different paths. Apparatus 500 is more complex module because it generates all the various sets of RF and control signals (506, 507, 508 and 509) and distributes among the various apparatus. Signal purity of apparatus 500 is very crucial and utmost care has been taken to fulfil it. Apparatus 300 receives the necessary second, third, fourth and fifth sets of RF and control signals (506, 507, 508 and 509) from 500 and finally processes to eighth set of wideband millimetre (Ka/Q band) wave signals. 300 is comprises of 330 and 350. 330 is divided into five different clusters viz., 360, 356, 370, 375 and 380 RF clusters respectively. 350 (D-1) amplifies one of the N eighth set of signal of 330 and produce the final output (302). Finally, one of the eighth set of signal is transmitted via 301 to the external world. Apparatus 300 also generate first, second and third sets of N status signals (S322A+, …, S348S-) and sends to 600 for taking crucial operational decisions. In another embodiment one of the N down converter 401, receives millimetre wave (Ka/Q band) N signals 402 from the N receiving elements 401 and send to N down converters. Apparatus 400 comprises of 410 and 430. 430 received Ku LO 303 from one of the N 330 and processes, equalizes and up converts to ninth set of N signals having double bandwidths then distributes between N 410 down converters. Signal 402 is further processed in 410 with the help of one of the N up converted signal 403, produces one of the N 405 signal, and sends to 600. Apparatus 430 of 410 receives a part of seventh signal as 303 and process it to generate N up converted 403 signals having double bandwidths. This processed signal within 430 is then divided in to N signals and up converted to ninth set of Ka/Q band signals (403A, … , 403N) whereas, bandwidth of these signals are double of the seventh signal. These N signals are phased matched and achieve equal amplitude within 430. Very low cost transitions (415A, …, 415N) have been used to pass these phased matched equal amplitude signals from Ku band sector to Ka/Q band sector. 415 require tight mechanical tolerance and high operator skillset. Except the down conversion 400 produces fourth set of detected signal statuses (405A, … S303-) and passed to 600 to take critical operational decisions.
[0011] RF layout of 300 and 400 is divided into various sectors (C/S, X, Ku and Ka/Q band) and each sector are well designed to protect signal leakage to produce clean signal (<55/60dB in-band and out of band) for the next sectors. Special care is take to design 331, 334,336, 340, 343, 345 (in Fig-6), 410, 412, 440, 443, 445 and 449 (in Fig-7) which assist to keep spurious and harmonics level down. Apparatus 400 achieves very good image rejection at Ka/Q band frequencies. Very low-cost Ku band Transitions 416 are used in compact size thus module becomes compact as well as lightweight. Isolation between various sets of RF signals within 500 is a challenge thus a compact layout plan has been introduced to house all the up converters thereby RF signals do not interfere between each other and at the same time module also becomes lightweight to integrate with antenna array.
[0012] In an embodiment, the central processing unit is configured to receive user inputs to take one more action based on the received status signals from the transmitter segment and the receiver segment.

The user interface is configured to at least display one more information of the said system and to receive one or more user inputs by the suitable means. The status signals received at the CPU (600) allow the user to take appropriate actions as required by the user.
[0050] Referring to figure 2, in the transmitter segment (300), each of the C/S-Ka/Q Band up converters (330N) is configured to receive at least one of each of the received signals i.e. one of the plurality of the second set of fixed frequency signals (506N), one of the plurality of fifth set of the control signals (507N), one of the plurality of third set of intermediate signals (508N), and one of the plurality of fourth set of intermediate signals ( 509N), and generate at least one status signal, at least one (as a part of seventh set of signals) wideband signal (302 ) and at least one KuLo signal (303) as a part of eighth set of signal,.
[0051] In an embodiment, the apparatus (200) is called as an antenna integrated Tx–Rx system 200 is comprises of three principal modules i.e., the transmitter segment (300), the receiver segment (400), and the Local Oscillator & Control Signal Generation Unit (LoCSGU) (500), which are communicatively coupled.
[0052] In one embodiment, the apparatus (200) receives a fixed frequency signal (610) and a first set of control signals (6201, …, 620N), known as first set of input signals, from the apparatus (600) and produces a plurality of millimetre wave, that is also referred as eighth set of wideband Ka/Q band signals (302N), and a plurality of C/S narrowband signals that is also referred as tenth set of signals (405N) for transmission as well as for further down conversion respectively. The apparatus (200) also generates first, second, third and fourth sets of 4N+1pairs of status signals and sends to the apparatus (700) for crucial operational decisions.
[0053] In an embodiment, the transmitter segment (300) receives second, third, fourth and fifth sets of radio frequency (RF) signals and a plurality of control signals respectively, from the Local Oscillator & Control Signal Generation Unit (LoCSGU) (500).
[0054] In one aspect of the embodiment, the Local Oscillator & Control Signal Generation Unit (LoCSGU) (500) is directly coupled with the C/S-Ka/Q Band up converters (330) to receive at least one sognal from the second (506), third (508 N), fourth (509 N) and fifth (507N) set of intermediate and control signals to generate seventh intermediate band KuLo signal (303) and one of the final eighth set of output signals (302). In another aspect of the embodiment, the receiver segment (400) and the Local Oscillator & Control Signal Generation Unit (LoCSGU) (500) are isolated electrically as well as mechanically and the receiver segment (400) is not communicatively coupled with the Local Oscillator & Control Signal Generation Unit (LoCSGU) (500). Further, electrical isolation between the transmitter segment (300) and the Local Oscillator & Control Signal Generation Unit (LoCSGU) (500) are taken care by separating these two RF modules mechanically and communicatively coupled via. wideband low-cost vertical transitions, high speed data links, flexible/semi rigid cables or by other means.
[0055] In an embodiment, interconnection between the transmitter segment (300) and the receiver segment (400) are done by wideband waveguide, high-speed data links, flexible/semi rigid cables or by other means.
[0056] Referring to figure 3, each of the plurality of the second, third, fourth and fifth sets of signals (506N, 508N, 509N, 507N) are separately coming from the Local Oscillator & Control Signal Generation Unit (LoCSGU) (500) as inputs to each of the C/S-Ka/Q Band up converters (330N). The KuLo signal (303) is generated by splitting the seventh intermediate band signal from one of the C/S-Ka/Q Band up converters (330N) and fed to the DNU (430) of the receiver segment (400) to up-convert and phase matched equal amplitude signals having double bandwidth of the seventh set of signals.
[0057] In an embodiment, First, second and third sets of critical status signals are generated from each of the C/S-Ka/Q Band up converters (330A, …., 330N) and sent as a differential pair to the CPU (600). Operation of various sectors of the C/S-Ka/Q Band up converters (330N) depends upon the state of these differential status signals (3N). The amplifier (350N) is also integrated within the transmitter segment (300) to produce stated power and transmits through one of the plurality of antennas (301N). This method of operation made possible to transmit one or multiple Ka/Q band eighth set of signals from a fixed frequency signal (610) having frequency <100MHz.
[0058] In Figure 4, each of the plurality of Ka/Q-C/S Band down converters (410N) is connect to at least one antenna (401N) and configured to receive a plurality of wideband signals (402N). The received wideband signals are down converted with the help of one of ninth set of signals (403N) and produces a tenth set of signals (405N) also known as narrowband signals, which is further transmitted to the apparatus (700).
[0059] The receiver segment (400) also receives at least one of the seventh set intermediate band signals (303) also known as KuLo signals and generates a ninth set of signals (403N) have a double bandwidth of the seventh signal (303) by the help of DNU (430). Fourth set of (N+1) pair of status signals (404N) are generated within the receiver segment (400) and sends to the control and processing unit (600) as a critical operational inputs.
[0060] In Figure 5, the LoCSGU (500) receives a fixed frequency signal (610) and a plurality of control signals (620) via high-speed data link or flexible cables or a suitable communication means, from the control and processing unit (600). The LoCSGU (500) produces a second set of a fixed frequency signals (506N), a third and a fourth sets of intermediate band RF signals (508N and 509N) and a fifth set of control signals (507N¬) for the transmitter segment (300). Physically, the LoCSGU (500) is an internal part of the transmitter segment (300). Thus, the signals (506N, 507 N, 508N, and 509N are communicatively coupled with the transmitter segment (300) by means of broadband vertical transitions, cables, high speed data links or the like.
[0061] Figure 6 illustrates an internal architecture and method of operation of the C/S-Ka/Q Band up converter module (330), the C/S-Ka/Q Band up converter module (330) is internally divided into five principal RF clusters, viz., C/S – Band (360), X – Band (365), Ku – Band (370), a status signal detection module (375) and Ka/Q – Band (380) clusters. The C/S – Band (360) comprises of frequency select device (331) and gain block (332). the X-band section (365), comprises of multiplier unit (321), intermediate band frequency select device (223) and gain block (324). Ku Band Section (370), comprises of mixing element (333), very sharp rejection frequency select devices (334) and (336), gain blocks (335), (325), and (338), splitter (336) and (326), adjustable attenuator (339) and Ku band frequency select device (340). Detection section (375), comprises of high pass filtering section (327), detector (328) and detected signal processing unit (329). Ka/Q band block (380) comprises of frequency multiplier (341) to upconvert a part of seventh signal (5092), mmWave band, a gain blocks (342) and (347), very sharp rejection frequency select devices (343) and (345) mixing element (344) to mix one of the fourth set of signal with up converted seventh signal to produce one of the eighth set of signal, splitters (346) and (348) and a detector unit (349).
[0062] In one embodiment, the C/S – Band cluster (360) receives one of the third set of intermediate band signals (508N) and rejects further unwanted spurious and harmonics of the intermediate band signal (508N) by the help of sharp rejection frequency select device (331) wherein, an amplifier (332) provides gain to the signal (509N) required for the mixer (333). One of the second set of fixed frequency signals (506N) is received by the X-Band cluster (365) and multiplied by N at a multiplier (321) and generates a sixth set of a narrowband LO signals, (5061) (wider than 508 signal bandwidth). The module intermediate band frequency select device (323) purifies the sixth signal (5061) and gets amplified by an amplifier (324). One of the third set of signals (508N) and one of the sixth set of signals (5061) are mixed by the mixer (333) and up converted to a Ku band a seventh set of signal (5091) (wider than (508N) and (5061) signal bandwidths), having narrow bandwidth within the Ku band cluster (370). The seventh set of signal gets purified by a Ku/K band frequency select devices (334), (336) and (340) and amplified by amplifiers (335) and (338) within the cluster (370) to ensure clean and adequate signal level to a next sector. The seventh set of signal (5091) splits into two signals viz., 5092 and 5093 by using a splitter (337). The signal (5093), a part of seventh set of signals is used to produce the KuLo signal (303) and input of the status signal detector module (327). The KuLo signal (303) is generated within one of the pluralities of the Ka/Q-Band up converters (330N) module and the port of 303 for other modules is terminated. The signal (5092) is multiplied by a multiplier (341) and produce the signal (5094) Ka/Q band signal. The signal (5094) is amplified and passed through the module (342) and (343). One of the fourth set of signals (509N) is mixed with the signal (5094) by using a mixing element (344) and up converted to one of the eighth set signals (5095) having wide bandwidth. The module (345) finally rejects all the spurious components for wideband whereas, the single-pole double-throw (SPDT) RF switches (346) between signal the signal (5096) and the signal (5097) to select either signal ports (302) or (360). The signal (5094) detected and processed through a module (347), (348) and (349) to generate one of the third set of status signals (355S1¬). The signal (5097) directly fed to the amplifier (350) to produce final output signal i.e a wideband signal (302).
[0063] In another embodiment, one of the seventh set of signals (split by a splitter (326)) is fed to the high pass module (327) and the detector module (328) to detect and produce one of the second set of status signals and directly fed to a P-detector circuit (329). One of the sixth set of signals (322N) is detected and processed within a module (239) and generates one of the first set of status signals. The P-detector circuit (329) also receives the status signal (355S1) from Ka/Q-Band cluster (380) and processes further and generates first, second and third sets of differential TTL status signals. Channelling of the clusters (360, 365, 370 and 380) are carried out very carefully to restrict unwanted signals from one cluster to another cluster. Individual module sealing has been done to enhance signal purity. All the five RF clusters are compactly housed within one side of a mechanical housing. Thereby isolation between various clusters is taken care keeping physical separation between RF clusters. Components used in modules of (360, 365, 370, and 375) are carrier based but components in (380) and (350) are modular type to arrest signal leakages.
[0064] In Figure 7, an internal architecture of the Ka/Q-C/S Band down converter (410) and its method of operation have been explained. the Ka/Q-C/S Band down converter (410) comprises of four major RF clusters DNU (430), Ku-Band (444), Ka/Q Band (460), and C/S Band (470). The clusters Ku-Band (444), Ka/Q Band (460), and C/S Band (470) and marked area of the DNU (430) are housed in one side of the housing and remaining portion of the DNU (430) is housed another side of the same housing.
[0065] In one embodiment, the Ka/Q-C/S Band down converter (410) receives one of the seventh set of signals (303N) having narrow bandwidth from the C/S-Ka/Q Band up converters (330N) of the transmitter segment (300). Further, the unwanted spurious of the KuLo signal (303) are rejected by the module (409) and amplified by an amplifier (411) then, harmonics generated after amplification is rejected by the module (412). Apparently cleaned and amplified signal is fed to a (N+2) way splitter (413) to produce N+2 signals. In one embodiment, the N+2 signal is similar to KuLo signal (303N). Channelling of each path of output of the splitter (413) is carried out with utmost care. The DNU module (430) is compact, and each channel is physically separated by metallic wall. Phase and amplitude of each path is matched by the help of a phase matcher (414) and (415) respectively. Low-cost wideband vertical transition (416) is used to pass the KuLo signal (303) to another side of the housing.
[0066] In an embodiment, a narrowband seventh set of signals (303N) is up converted in a module (417) and generates a ninth set of Ka/Q band signals (403N) have double bandwidth of the KuLo signal (303N). the ninth set of the Ka/Q band signals (403N) is further amplified by N time using an amplifier (442) and passed through a module (443). In another embodiment, the Ka/Q-C/S Band down converter (410) receives a plurality of wideband signals (402N) from an plurality of antennas (401N). One of the wideband signals (402N) is passed through one of a module (440) which rejects the images and other unwanted wideband spurious frequencies. One of the wideband signals (402N) and one of the ninth set of LO signals (403N) is mixed by a mixer (441) and down converted to one of the tenth set of narrowband signals (4021). One of the K band sharp rejection FSD module (444) is used to reject the Ka/Q band unwanted LO leakage signal 403 and its harmonics leaking from 430 DNU section into 470 IF cluster and to pass 4021 with minimum attenuation. It helps to keep one of the signals (405N) clean up to several octaves. The module (440) is very crucial to reject the signal (403) at the (402) signal port which intern stops back radiation of the signal (403) through receiving element or the antennas (401N). One of the narrowband signals (4021) is amplified by an amplifier (445) and splits by a splitter (447) and generates a signal (4022) and (4023). Now the signal (4022) is further amplified by an amplifier (448) to generate required level of the signal (405N) by adjusting a module (449). The modules (446) and (450) are used to pass very narrow band signals and to stop all the spurious and harmonics of the (445) and (448). The modules (446) and (448) also assists to reject the signal (403). The amplifiers (445) and (448) have been selected thus its gain characteristics go zero or negative at signals (403N) frequencies. The signal (4023) is fed to modules (451) and (452) to generate status signals. A status signal detection module (418) processes the detected signals further and generates fourth set of differential TTL status signals. Components used in the module (470) are realized as a single board which ease the assembly process. The Ka/Q band modules used in cluster (460), made as a drop in module to keep signal leakage less to the other sectors. Each channel is isolated from nearby RF sectors by absorber clad multilayer metallic covers. Mechanical channels are layed-out carefully to arrest higher order modes.
[0067] In Figure 8, an internal architecture of the Local Oscillator and Control Signal Generation Unit (LoCSGU) (500) and its method of operation are described. The LoCSGU (500) is densely packed RF module divided into various RF clusters to generate all the necessary RF and control signals for the transmitter segment (300). In one embodiment, a frequency generator (534) generates VHF signals (501) whereas frequency of (501) is less than 100MHz, and the module (535) reject all the unwanted harmonics of the signal (501) and gets adjusted to required level by a module (536). A splitter (537) splits the signal (501) for modules (538) and (540). The modules (538) and (540) makes the signal (501) into two split signals (5011) and (5012) and passed through modules (539) and (541).
[0068] In an embodiment, the first set of fixed frequency signals (610N) received at a 3-way splitter and splits into three signals i.e. (6101), (6102), and (6103). The signal (6101¬) passes through a module (523), a module (524), and a N-way splitter (525) and each of the split signals is then amplified by an amplifier (526N) then generates a second set of fixed frequency signals (506N) also referred as a plurality of the fixed frequency signals (506A, …., 506N).
[0069] In an embodiment, the split signal (6102) is mixed with the signal (5011) at a mixer (529) and up converted to a signal (5013) and gets purified and amplified by modules (530) and (531) for a N-way splitter (532). The N-way splitter (532) splits the received signal (5013) into multiple signals and each of the split signals are passed through at least one amplifier (526) to produce a plurality of intermediate RF signals (509N) also known as fourth set of signals (509A, …., 509N).
[0070] In an embodiment, the split signal (6103) gets amplified by an amplifier (542) and processed with the signal (5012) by a mixer (543) and up converted to a signal (5014). The signal (5014) is passed through a module (544), a module (545), a N-way splitter (546) to split the signal (5014) into multiple signals and each of the split signals are amplified by at least one amplifier (547N) and generates a plurality of intermediate RF signals (508N) also known as third set of signals (508A, …., 508N). The first set of control signals (6201, …, 620N) are received at a control signal unit (527) and produce a fifth set of control signals (507N) also known as a plurality of control signals (507A, …., 507N). Packaging of all channels has been carried out carefully to keep minimum leakage between the signals 6101, 6102 and 6103 signal pathways. Metallic walls and absorber clad individual metallic covers are used to minimize the signal interferences between 6101, 6102 and 6103 signal channels. Generation of various RF and control signals in multiple numbers is made possible by receiving only one fixed frequency signal and first set of control signals from the Control and processing unit (600).
[0071] Referring to Figure 9A-9C. The graph depicted in Figures 9A – 9C plot the frequency of the input IF signal on the vertical axis (Y axis), the output up converted RF frequency of spurs from the up converter on the horizontal axis (X axis) for a given LO frequency [in the example illustrated in Fig 9A – 9C, the LO frequency is (X – 0.5) GHz, X GHz and (X +0.5) GHz, but other frequencies may also be chosen]. Each line on the plot is marked with two numbers (m, n) wherein the first number, m refers to a factor by which the input IF signal frequency is multiplied, and the second number, n refers to a factor by which the second input, i.e., LO frequency is multiplied. Further, the order of the spur is determined as the sum of absolute value of m and the absolute value of n. The shaded box in Fig 9A – 9C represents the output intermediate RF frequencies of the up converter 330 for which the input LO frequencies are (X – 0.5) GHz, X GHz and (X + 0.5) GHz, and the desired output RF frequencies of Ku GHz to (Ku + 2.0) GHz. For an instance, the (1, 1) line, the value ‘1’ refers to the fundamental of the input IF signal and the value ‘1’ refers to the fundamental of the LO input of X GHz.
[0072] Figures 9A – 9C demonstrate the generation of spurs in the up-conversion process, as performed by up converters of the Ka/Q Band up-converter (330N). Figures 9A – 9C present plots of spur generated by the mixer (333) in the C/S to Ku band up conversion for various X band LOs illustrated in figure 6. Such spurs are the product of imperfections in the mixing process taking place within the up converters. The spur frequency, and hence its impact to the desired performance depends on the input frequency provided to the up converter, LO used by the up converter and the desired output signal frequency of the up converter. Note again that in each case presented, the generated spurs avoid any fundamentals (0, n), and comprise mostly higher order spurs that can be readily avoided by FSDs. The vertical lined boxes represent an analysis of the spurs potentially generated for various X band LOs by the up converter.

It is to be noted that in each case presented, the generated spurs avoid any fundamentals (0, n), and comprise mostly higher order spurs that can be readily avoided by FSDs. The forward slashed boxes represent an analysis of the spurs potentially generated by up converter.
[0074] Figures 11A – 11C demonstrate the generation of spurs in the down conversion process, as performed by down converter of Ka/Q-CS Band down converter (410). Fig 11A – 11C present plots of spur generation by the module (441) in the Ka/Q – C/S band down conversion for various Ku band LOs illustrated in figure 7. Such spurs are the product of imperfections in the mixing process taking place in the down converter. The spur frequency, and hence its impact to the desired performance depends on the input frequency provided to the down converter, LO used by the down converter, and the desired output signal frequency of the down converter. Note again that in each case presented, the generated spurs avoid any fundamentals (0, n), and comprise mostly higher order spurs that can be readily avoided by FSDs. The vertical lined boxes represent an analysis of the spurs potentially generated for Ku band LO by the down converter module (410).

At step 9922, the received fixed frequency signal (610) splits by the 3-way splitter (522) into three signals (6101, 6102 and 6103) as shown in figure 8. This can be accomplished, for example by 3-way splitter of the LoCSGU (500), whereas split signals gets amplified by the modules (523, 528 and 542) respectively. At step 9923, the first part of the three fixed frequency signal processed into second set of the fixed frequency signals, in one embodiment, second component of the split signal is up converted into third set of intermediate signals and in another embodiment, third part of split signal is up converted into fourth set of intermediate band signals, first set of timing and control signals has also been processed and split into fifth set of control signals. At step 9924, one of the second set of fixed frequency signals is up converted and processed into X band sixth set of signals as shown in figure 6 whereas, sixth signal is used as LO to process the one of the third set of signals. In one embodiment, one of the sixth set of intermediate band signals is processed and generates one of the first set of detected signals.

At step 9942, the receiver segment (400), receives a plurality of wideband millimetre wave signals from plurality of antennas (401N) as shown in figure 2. At step 9943, each of the received plurality of wideband millimetre wave signals (402N) are down converted by at least one of the Ka/Q-C/S Band down converters (410N) to the tenth set of narrowband signals (405N). At step 9944, one of seventh set of signals is processed to generate a fourth detected signals. The tenth set of signals (405N) are processed to generate fifth set of the detected signals as shown in figure 7.
