N2 - Abstract-InP Gunn devices with graded doping profiles were evaluated for second-harmonic power extraction above 260 GHz and third-harmonic power extraction above 400 GHz. The best devices generated radio frequency (RF) output power levels of more than 3.5 mW at 275-300 GHz, 1.6 mW at 329 GHz, and 0.7 mW at 333 GHz. The highest observed second-harmonic frequency was 345 GHz. Two devices each in an in-line power combining circuit generated 6.1 mW at 285 GHz and 2.7 mW at 316 GHz with combining efficiencies of more than 65%. In a thirdharmonic mode, the best devices generated 45 μW at 409 GHz, 40 μW at 412 GHz, and 40 μW at 422 GHz.
