A 230 GHz MMIC-Based Sideband Separating Receiver
Abstract
A 230 GHz MMIC-based, cryogenically cooled sideband-separating receiver is presented. Utilizing 30 nm InP HEMT MMICs for the front-end LNA and mixers, the system is cooled to 27 K and operates from 200 GHz to 260 GHz. The system is measured in a cryostat that couples the hot, cold and test signal to the DUT without passing through an optical window, reducing losses in the optical path. An average single-sideband (SSB) noise temperature of 92 K is measured across the band. Sideband rejection ratios are between 10 and 15 dB.
