ABSTRACT:
A power control system (12) for a satellite (10includes 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.
