摘要

提出了一种采用ƒT /ƒmax = 280/435 ghz SiGe技术的工程版单片220 ghz接收机前端。前端由一个三级差分LNA和一个次谐波混频器组成。220-GHz LNA的分离提供15db增益和28ghz带宽。当泵浦0-dBm, 110-GHz的LO信号时，集成的下变频器产生16 dB的转换增益，15 dB的DSB NF和30 ghz的带宽。

A 220GHz subharmonic receiver front end in a SiGe HBT technology

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.
