System And Method For Managing The Operation Of A Travelling Wave Tube Amplifier

Abstract: The proposal is a satellite system (10) comprising a radio frequency signal amplifier device (100) comprising a control and supply module (1040) and a plurality of travelling wave tubes (1020-n). The module (1040) is configured to apply to at least one of said tubes an anode voltage operating value, generating a cathode current in response. The module (1040) is moreover configured to measure at least one sum of the cathode currents that is associated with said plurality of tubes, said at least one measurement of the sum of the cathode currents being implemented on the basis of a single measuring circuit (1044), and to determine at least one corrected anode voltage operating value, associated with said at least one of said tubes, on the basis of said at least one measurement of the sum of the cathode currents.
