Abstract :
A widely tunable oscillator with a center frequency of 94 GHz including a two stage buffer amplifier has been designed and fabricated, The output power was 6 mW. The mechanical tuning range by removing air-bridges was 18 GHz. The electrical tuning range was 8 GHz. The noise performance was better than -67 dBc/Hz at 1 MHz from the carrier.
