Abstract :
The paper presents the design and simulation investigation of a low-loss fixed-tuned subharmonically pumped mixer at 300-350GHz, utilizing GaAs Schottky planar diodes. The antiparallel diodes pair is from Rutherford Appleton Laboratory (RAL), flip-chip mounted on a 50μm-thick suspended quartz substrate. The simulation performance of the mixer exhibits a conversion loss below 10 dB over the range from 302GHz to 350GHz, with 3 mW of local oscillator (LO) power.
