Abstract
A power up-mixer is proposed in this letter. A merged CMOS linear power amplifier (PA) and mixer allows low current consumption and smaller chip size than a conventional integrated transmitter including a mixer and a CMOS linear PA. The chip is fabricated in a 0.18 mum CMOS process and in an integrated-passive-device. Measurements show a drain efficiency of 27% at 27.2 dBm of 1 dB compression point (P1dB) output power from 1.75 to 1.95 GHz. Power conversion gain is 26.4 dB and LO leakage is -43 dBc.
