Gunn-diode oscillator at 95 GHz

Abstract

The results of Gunn-diode-oscillator development at 90 to 94 GHz are reported, along with a discussion of the devices and circuit used. The best performance obtained was 25 mW output power (at 30°C heatsink temperature) with a d.c.-to-r.f. conversion efficiency of 0.6% at an operating frequency of 93.7 GHz.
