Abstract :
A K-shaped antiparallel microstrip amplifier having four high-efficiency avalanche diodes has provided 400 W at 1.01 GHz with 8.8 dB power gain and 1.23% bandwidth. A novel fishbone-shaped tuning plate has worked not only to widen the bandwidth to 10%, but also, together with stagger-tuned antiparallel pairs, to increase the gain bandwidth from 94.8 MHz to 447 MHz.
