Development of a 4.7-THz Waveguide Schottky Diode Balanced Mixers
Paper in proceeding, 2025

This paper focuses on developing 4.7-THz waveguide-based Schottky barrier diode mixers. An integrated, singly balanced mixer using ultra-small Schottky barrier diodes was realized on a 2-mum GaAs substrate and mounted in a micro-milled waveguide housing with integrated smooth-walled horn antennas. The waveguide module was machined in aluminum using a 5-axis CNC machine with a high-speed air-bearing spindle.
