Abstract

PURPOSE:To compensate the reduction of the output power of a device by detecting the change of the passing phase characteristic of respective amplifiers and adjusting the phase shifting quantity of a phase shifter connected to the amplifier when plural channels are amplified with plural amplifiers. CONSTITUTION:A signal inputted to respective terminals of an N number of signal input terminals of a power coupler 5 is equally divided, and outputted to a 2N number of signal output terminals 2. Respective outputs of the power coupler 5 are inputted through a phase shifter 8 and an amplifier 7 to the 2N number of signal input terminals 3 of a power coupler 6 and synthesized by the power coupler 6 and output from the N number of signal output terminals 4. On the other hand, an N number of detecting terminals 9 is provided at a first step hybrid coupler 10 of the power coupler 6, and when the passing phase characteristic of the amplifier 7 is changed, a leakage power is outputted, the output power of the device is reduced and by a power detector 13 and a phase controller 14, the phase shifting quantity of the shifter 8 is adjusted so as to cancel the change of the above-mentioned passing phase.
