A 2.4GHz fully integrated power amplifier with an on-chip balun for embedded WLAN applications with direct battery connection (2.3-5.5V) is presented. With a switched programmable feedback bias network, the PA can deliver 23.5dBm to 28.4dBm CW saturated power and 18.2dBm to 23.2dBm OFDM linear power (-25dB EVM) with PAPD when the supply varies from 2.3V to 5.5V. The PA occupies 1.2mm2 in 65nm CMOS.
