摘要：
This letter presents the design and fabrication of a low-noise fixed-tuned 300-360-GHz sub-harmonic mixer, featuring an anti-parallel pair of planar Schottky diodes fabricated by the University of Virginia and flip-chipped onto a suspended quartz-based microstrip circuit. The mixer exhibits a double side blind (DSB) equivalent noise temperature lower than 900 K over.1.8% of bandwidth (300-360-GHz), with 2 to 4.5 mW of local oscillator (LO) power. At room temperature, a minimum DSB mixer noise temperature of 700 K and conversion losses of 6.3 dB are measured at 330 GHz.
