Monolithic Integrated Antenna and Schottky Diode Multiplier for Free Space Millimeter-Wave Power Generation

This letter presents a novel monolithic integrated frequency multiplier circuit for free space power generation in the W-band (75-110 GHz). The circuit is based on a submicrometer GaAs Schottky diode monolithically integrated with a slot antenna on a GaAs semi-insulating substrate. The fabricated diode with an air-bridged Schottky contact and a U-shaped ohmic contact showed an ideality factor of a...
