ABSTRACT:
A microwave power amplifier/combiner which is composed of .pi./2 hybrid coupler. This microwave power amplifier/combiner is constructed by associating a .pi./2 phase shifter with the .pi./2 hybrid coupler to form a 2-amplifier/combiner having a single input/output port and employing the 2-amplifier/combiner as one unit. 2.sup.N -amplifier/combiner can be constructed by employing a desired number of the unit 2-amplifier/combiner. According to this amplifier/combiner, the microwave power amplifier/combiner which combines the outputs of a large number of power amplifiers can be combined by employing a small number of .pi./2 hybrid coupler.
