ABSTRACT:
A compound semiconductor device is comprising a compound semiconductor substrate (219) having a ground plane (205); an active element (201) disposed on the substrate; a passive element (211) disposed on the substrate and electrically coupled to the active element; and an insulating layer (202) adjacent the substrate and interposed between the passive device and ground surface such that there is no resistive ground path from the passive device to the ground surface.
