A W-band 65nm CMOS transmitter front-end with 8GHz IF bandwidth and 20dB IR-ratio

Abstract

A W-band transmitter front-end has been implemented in 65 nm CMOS. The output power is higher than +4 dBm from 77 GHz to 94 GHz with an image rejection ratio from 15 dB to 25 dB. The highest 1 dB output compression point is +2.2 dBm with +6.6 dBm maximum power at 85 GHz. The transmitter draws 100 mA from a 1.2 V supply.
