Abstract :
A 2.4 GHz CMOS power amplifier with a distributed LC power-combining network and improved linearization for high-power WLAN applications is presented. With a 3.3 V supply the PA produces a saturated power of 31.5 dBm with peak PAE of 25 %. By utilizing multiple linearization techniques, an EVM of -25 dB is achieved at 25.5 dBm for the 2.4 GHz band. The PA occupies 2.7mm2 in 65 nm CMOS.
