Abstract :
A low-power UHF-to-low-IF downconversion mixer was implemented in a 0.5-μm CMOS process. This mixer is designed as the second-block of an integrated low-IF receiver under development for deep space applications. The mixer dissipates 5.4 mW from a 2.5-V supply. LO power requirement is -10 dBm. Voltage conversion gain is 20.8 dB. Single side-band noise figure is 9.2 dB at 2 MHz IF. Input 1-dB compression point is -21 dBm while the IIP3 point is at -13.4 dBm. The entire mixer occupies a die area of 0.3 mm × 0.26 mm. Low-power dissipation makes this mixer attractive for low-power highly integrated receiver applications.
