Abstract
An InP Gunn device designed for fundamental-mode operation in D-band was mounted on a diamond heatsink for improved heat dissipation. The highest RF output power measured was 56 mW at 128 GHz and 49 mW at 132 GHz with DC-to-RF conversion efficiencies above 2%. Typical phase noise is well below -100 dBc/ Hz at 500 kHz off the carrier. Devices tested in second-harmonic mode yielded more than 0.3 mW between 280 and 290 GHz
