Abstract :
In this work, theoretical and experimental investigations concerning power generation by second harmonic operation of self-pumped IMPATT diodes are described. The active device is characterised by a time-domain drift-diffusion model driven at fundamental and superimposed second harmonic frequency. The applied disc-type resonator structure is investigated by a commercial simulation program. Using a low parasitic encapsulation method and power combining of three active devices, 1 mW CW output power at 210 GHz was obtained, a value which was not achievable in fundamental mode operation so far
