Abstract :
Indium Phosphide TEO´s giving up to ¿ Watt C.W. power at 28.5 GHz with an efficiency of 3% have been prepared by an Integral Heat Sink technique. Efficiencies of 5.5% pulsed at 32.5 GHz and 2% C. W. at 50 GHz have also been observed. The device and circuit design are discussed with reference to the attainment of high frequency operation (> 40 GHz) aimed at powers in excess of 100 mw with a useful tuning range. Indications of low noise performance suggest a possible application as parametric amplifier pumps.
