  • Variable high power amplifier with constant overall gain for a satellite communication system
    Patent number: 7139526
    Abstract: A power control system (12) for a satellite (10 includes a high power amplifier circuit (28) that receives a saturated power output adjustment signal. The amplifier circuit (28) includes a programmable circuit (70). An electronic power conditioner (56) is coupled to the programmable circuit (70) and is configured to reset an operating set-point of said high power amplifier circuit (28) in response to the saturated power output adjustment signal. A high power amplifier (46) has a variable output power range and amplifies a received signal in response to change in the operating set-point. A channel amplifier (44) is coupled to the programmable circuit (70) and is configured to gain offset the received signal in response to change in the operating set-point.

  • Broadband High Efficiency Traveling Wave Tube Amplifier System
    Publication number: 20060234626
    Abstract: A power control system for a satellite receiving radio-frequency signals includes 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.
