ABSTRACT:
A push-pull power amplifier for amplifying an input signal is described where anti-phase signals are generated from the input signal using a first hybrid junction for driving a pair of transistors and where anti-phase transistor output signals are combined in-phase on an output line by using a second hybrid junction. An independent port may be added to the hybrid junction for isolating and terminating even order harmonics and even order intermodulation products.
