A K-band low voltage, highly linear Gilbert cell mixer is presented in this paper. The goal of this work is to achieve highest possible linearity when the supply voltage is as low as 2 V. The proposed low voltage mixer topology has been experimentally verified with a down conversion mixer fabricated in a 0.18-mum CMOS process. Utilizing PMOS devices in the transconductance stage and using a 2 V supply voltage, the mixer can down convert from 24GHz to 10MHz with an input referred third order intercept of +20dBm and a conversion gain of +2dBm, thus making it a candidate for single chip receiver applications
