Abstract
A phase-locked Gunn oscillator at 21 GHz for local oscillator application in a ow-noise radio astronomy receiver isdescribed. The oscillator gives a maximum CW power output of 60 mW, bias-tuning range of 40MHz, and DSB AM noise of—140 dBc in 1-kHz bandwidth at 1.4 GHz away from the carrier. The phase-lock scheme developed for the Gunn oscillator is highly versatile and can be used for phase-locking a variety of solid-state millimetre-wave sources.
