Abstract

A high output 1 dB compression point 60-GHz up-conversion mixer fabricated on 0.25 μm SiGe:C technology is presented. It is based on the Gilbert cell and integrated with LO passive stacked Marchand balun to convert the LO single ended signal into differential. It employs tuned load consisting of spiral inductor and MIM capacitor to match the differential output to 100 ohm and to attenuate the image signal by 15 dB in the middle of the band. The conversion gain is 2.2-dB in 61 GHz and varies within 2 dB over 9 GHz band. We achieve output 1-dB compression point of -3.4 dBm. To the best of our knowledge it is the highest output 1-dB compression point in silicon-based 60-GHz mixers. It consumes 10 mA from 3.3 V supply.
