Abstract

PURPOSE:To easily adjust an output power from a ground station, etc., by providing a variable attenuator and a control signal adjusting circuit to adjust this between a power distributor and a detector. CONSTITUTION:A part of an AGC amplifier output by a power distributor 5 is provided between the distributor 5 and a detector 6, responds to an external command, and is supplied through a variable attenuator 8 controlled by a control signal adjusting circuit 9 to output a digital control signal. The detecting output is compared with a reference voltage added to a comparison amplifier 7 and an input side variable attenuator 3 is controlled. Consequently, by the external command in accordance with a communication condition, the output adjustment of a satellite mounted AGC amplifier can be easily and surely executed.
