A Quasi-Optical Subharmonically Pumped Double Slot Mixer

Abstract:
In this paper, we describe the design, fabrication, and testing of a quasi-optical subharmonically pumped mixer that incorporates dual double slot antennas and planar Schottky diodes. RF and LO signals illuminate the mixer with orthogonal polarizations and are coupled to the double slot antennas through a hemispherical silicon lens. The design uses four SC2T6 planar Schottky diodes fabricated at the University of Virginia and mounted to the mixer circuit using silver epoxy. With an LO of 80 GHz and an RF signal at 161.8 GHz, this mixer has shown an approximate single sideband (SSB) conversion loss of 8 dB.
