90–120 GHz millimeter wave power head

Abstract

Power-voltage and frequency characteristics of power heads for 90–120 GHz TE10-mode millimeter waves are presented. Operation of the power heads is based on thermo-e.m.f. of hot charge carriers in silicon. The head has been tested both in the pulsed and continuous generation regime. The experiments were carried out in the power range of 2·10−3−4 W. In the pulse regime, the shortest pulse duration was 1μs.
