A mm-Wave CMOS Heterodyne Receiver with On-Chip LO and Divider

A heterodyne RX incorporates an LNA, RF and I/Q IF mixers, nested inductors, and a passive-mixer-based Miller divider. Fabricated in a 90nm CMOS process, the RX achieves an NF of 6.9 to 8.3dB from 49 to 53GHz with a gain of 26 to 31.5dB and an I/Q mismatch of 1.6dB/6.5deg. The circuit consumes 80mW from a 1.8V supply
