Abstract :
High-power and high-efficiency InP Gunn diodes which were made from wafers grown by LP-MOCVD have been developed in the millimetre-wave range. Average power levels in excess of 50 mW were obtained at 94 GHz with an efficiency of 3%, while an optimised structure operating at 75 mW has been obtained with an efficiency of 2.4%.
