ABSTRACT:
A microwave switching device replacing PIN diodes and operating at higher eeds requires reduced switching current. A field effect controlled device is utilized with no ground plane, for elimination of source-ground and drain-ground capacitance. Massive source and drain structures reduce terminal inductance. A low resistance active region provides dynamic switching capability improving over prior art devices in operating frequencies and speeds.
