ABSTRACT:
A power control system for a satellite receiving radio-frequency signals includes a digital processor and a traveling wave tube amplifier system and corresponding traveling wave tube. An anode voltage of the traveling wave tube amplifier system is used to modulate or saturate the current of the electron beam of the traveling wave tube so that the output power of the traveling wave tube amplifier system, from the saturated electron beam, is proportional to a waveform envelope of the radio-frequency signals. The digital processor controls anode and RF input signal amplitudes to the traveling wave tube and predicts necessary corrections.
