Abstract

PURPOSE:To attain compact constitution by constituting each unit amplifier by a hybrid integrated circuit incorporating a phase variable element capable of varying an output phase. CONSTITUTION:The unit amplifiers 31-3n are constituted by arranging matching circuit bases 12-14 on a base 11 and a diode chip 15 being a phase variable element and a transistor chip 16 interposed among them as one module by the hybrid integrated circuit technology. Thus, the phase of the output of the unit amplifiers 31-3n is adjusted by the phase variable element 15, the phase is matched by a power synthesizer 2 and a maximum power is outputted. In this case, since the phase variable element 15 is built in the hybrid integrated circuit incorporatedly in the unit amplifiers 31-3n, it is not required to provide a phase shifter separately from the amplifiers and the power synthesizing amplifier is made compact.
