Abstract

A monolithic downconverter for 94 GHz imaging arrays implemented in SiGe:C technology is presented. The downconverter consists of a three stage differential LNA with lumped matching networks and a polyphase subharmonic mixer. It yields 20 dB conversion gain at 94 GHz with an input 1 dB compression point of -31 dB and a current consumption of 45 mA at 3.3 V supply voltage. The total required die area of the complete downconverter (excluding pad frame) is 0.1 mm², making it particularly suitable as a front-end in multi-channel receiver systems.
