High-power microwave amplifier using an antiparallel avalanche-diode pair

Two high-efficiency avalanche diodes, each placed in opposite polarity to the other at the ends of an approximately one-half wavelength transmission line, have worked as a high-power reflection-type amplifier. The circuit configuration is called an anti-parallel pair of high-efficiency avalanche diodes. The antiparallel amplifier has provided 200-W pulsed output power with a 10-dB gain at 1.01 GHz.
