Abstract
A monolithic 220-GHz receiver front-end manufactured in an engineering version of an ƒT /ƒmax = 280/435-GHz SiGe technology is presented. The front-end consists of a three-stage differential LNA and a subharmonic mixer. A breakout of the 220-GHz LNA provides 15 dB gain and a bandwidth of 28 GHz. The integrated downconverter yields a conversion gain of 16 dB, a 15-dB DSB NF, and a 30-GHz bandwidth when pumped with a 0-dBm, 110-GHz LO signal.
