Analysis of a 100-GHz double-drift IMPATT oscillator

The purpose of this paper is to analyze and characterize in some detail a 100-GHz double-drift IMPATT oscillator. The small-signal and large-signal behavior of the diode has been analyzed using a semiconductor-analysis computer program. It is suggested that previously reported experimental results have been achieved with the aid of second-harmonic tuning and that 150-GHz single-frequency operation is possible with the present diode structure.
