Abstract

A compact 129-140 GHz Gilbert-cell mixer for up-conversion and 127-140 GHz image-rejection (IR) resistive mixer for down-conversion are realized for a 140-GHz transceiver in 28 nm bulk CMOS technology. A wide 7.5-GHz intermediate frequency (IF) tuning range is obtained for both mixers. The measurement results show a 6 to 12 dB conversion loss for the Gilbert-cell mixer with a layout size of 0.455mm2including the probing pads where the core area is only 0.005mm2. The mixer consumes only 8 mW of DC power and exhibits better than 42 dB LO-to-RF isolation. The resistive mixer shows 20 dB image rejection ratio and better than 40 dB LO-to-RF suppression with only 0 dBm LO-power. The layout size of the mixer is 0.543mm2including the probing pads.
