A 600 GHz planar frequency multiplier feed on a silicon dielectric-filled parabola

Abstract

A novel all-planar quasi-optical Schottky varactor diode frequency doubler has been fabricated and has produced more than 1 mW of output power at 600 GHz with an approximately 2 percent conversion efficiency. This simple-to-assemble all-planar diode multiplier could replace complicated waveguide blocks commonly used at submillimeter-wave frequencies to provide local oscillator power for terahertz receiver components.
