This paper describes the design, simulation and measurement of a Schottky sub-harmonic mixer working around 370GHz. The device is based on an anti-parallel pair of planar Schottky diodes flip-chip mounted onto a single quartz-based microstrip circuit. The best DSB noise temperature of about 3500K is measured with LO at 184.5GHz. The performance of the mixer at room temperature and the liquid nitrogen...
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...
