Abstract :
We have developed HEMT-based sideband-separating receivers operating in the 180 to 270 GHz and 620 to 660 GHz bands. These receivers utilize 30nm InP HEMT MMICs for the front-end low-noise amplifiers and balanced mixers cryogenically cooled to 20K. This paper presents the room and cryogenic temperature characterization of the receiver front-end system.
