  • Abstract
    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 temperature are also compared. The measurement shows at least 10% reduction of the mixer noise by cooling.
