A 1.5-V 5 GHz CMOS Down-conversion mixer for wireless LAN Applications

This paper describes a 1.5-V 5 GHz I/Q down conversion mixer in a 0.18-μm CMOS process. The mixer achieves a conversion gain of 12.7 dB within 1-dB compression point (iCP
_1dB
) of -15.83 dBm. It also achieves a double side band (DSB) NF of 13.5 dB. The mixer's IIP3 is -5.94 dBm. The mixer consumes only 5.72 mA of current from a 1.5-V power supply.
