Abstract

A high-power Schottky diode frequency multiplier chain at 360 GHz, with a 3 dB bandwidth above 20 GHz is presented. The cascaded frequency doublers show peak efficiencies of 35% and 23% at 180 and 354 GHz, respectively. While the 180 GHz doubler generates a maximum power of 69 mW at 300 mW input, the second stage doubler delivers 12 mW output at 360 GHz. Both doublers consist of low parasitic GaAs Schottky diode circuits optimized to handle high input powers, and neither exhibit saturation at the highest applied power.
