%X This paper presents a fully integrated broadband low power high isolation subharmonic mixer. The proposed mixer achieves a double-balanced architecture by adopting a single-to-differential frequency-doubling technique, and improves port-to-port isolations. The mixer fabricated by tsmc 0.18 ¦Ìm Mixed Signal CMOS process achieves maximum power conversion gain of 7.1 dB, input third-order intercept point (IIP3) of -6.9 dBm, input second-order intercept point (IIP2) of 33.5 dBm, and single side-band noise figure of -19.6 dB over the 2.3-5.8 GHz fourth generation of mobile phone communications standards (4G) frequency band. The LO-RF, LO-IF and RF-IF isolations are 82.8 dB, 66.5 dB and 62.3 dB, respectively. The measured power consumption is 2.95 mW at a 1.8 V power supply.
