A wideband Gilbert cell up-converter in 90 nm CMOS for 60 GHz application

Abstract

This paper presents a fully integrated 60 GHz double-balanced Gilbert cell up-conversion mixer implemented in 90 nm LP CMOS technology. The mixer has been designed for very low DC power consumption (11 mW) and wideband performance to cover the four channel bands of the IEEE802.15.3c standard. Due to measurement limitations different transformers have been designed for IF, LO and RF path to facilitate the measurement of the mixer with single-ended equipment. The up-converter achieves a flat conversion gain of -8 dB and output power at 1 dB gain compression point of -11 dBm for channels.
