Abstract
A 122 GHz subharmonic receiver for imaging and sensing applications has been realized, which consists of a single-ended LNA, a push-push VCO with 1/32 divider, a polyphase filter, and a subharmonic mixer. It is fabricated in SiGe:C BiCMOS technology with fT/fmax of 255 GHz/315 GHz. The down-conversion gain of the receiver is 25 dB at 127 GHz, and the corresponding noise figure is 11 dB. The 3-dB bandwidth reaches from 125 GHz to 129 GHz. The input 1-dB compression point is at -40 dBm. The receiver consumes 139 mA at a supply voltage of 3.3 V.Keywords
