This letter presents a 24-GHz down-conversion mixer with built-in linearizer in 0.18-mu m CMOS process. The mixer attains -4.5 +/- 0.6 dB conversion gain and 23-dBm IIP3 with 5-dBm local-oscillator power by adopting double-balanced Gilbert-cell mixers with a distributed derivative superposition linearizer. The improvement of IIP3 is 9 dB. The dc power consumption of the proposed mixer is 16 mW. This mixer has the best IIP3 compared with other published CMOS mixer in the K-band.
