Abstract

This report presents a 2.4 GHz microwave power amplifier and down-converter, which were fabricated by a standard 0.35 /spl mu/m 1P4M CMOS process technology. The CMOS power amplifier delivered a 17.5 dBm output power at 2.4 GHz operation, with a maximum power added efficiency of 16%. A CMOS integrated down-converter, including an oscillator and a double-balanced mixer in the 24 GHz band, was also introduced. The oscillator's working frequency is 2.36 GHz with a -3 dBm power level. The measured conversion gain and port-to-port isolation of this double-balanced mixer, were -3 dB and 25 dB, respectively.
