Abstract

This paper describes the demonstration of 77 GHz gallium nitride (GaN) power amplifier (PA) on a silicon substrate. The PA monolithic microwave IC (MMIC) was fabricated by using developed AlGaN/GaN HEMTs on Si with double-deck shaped (DDS) field-plate gate with fmax of 160 GHz (fT = 70 GHz) and a breakdown voltage of over 70 V. The demonstrated 3-stage power amplifier exhibited output power with 20.1 dBm at 77 GHz for 18 V drain bias.
