A Low VSWR 340 GHz 2SB Schottky Receiver for Earth Observation Applications

摘要

A waveguide integrated 2SB Schottky receiver operating in the 320-360 GHz band with a performance similar to state-of-the-art DSB Schottky mixers is demonstrated. The unique receiver topology utilizes a low RF and LO VSWR design leading to better mixer performance and superior response for the radiometer system in general. On average a 15 dB SBR is measured over the RF band and a LO return loss of 15 dB broadband.
