Abstract
A 35 GHz dielectric resonator oscillator(DRO) using GaAs Gunn diode in microstrip configuration has been designed and developed. The oscilla tor, with an integral waveguide-to-microstrip transition, delivered an output greater than 18 dBm. Phase noise of the oscillator is found to be better than -80 dBc/Hz at 100 KHz away from the carrier. A frequen cy drift of about +/- 25 MHz has been observed over the temperature ra nge from -10 degrees C to 50 degrees C.
