This paper describes the design and evaluation of a power amplifier (PA) for WLAN 802.11n in 65nm CMOS technology. The PA utilizes 3.3V thick-gate oxide (5.2nm) transistors and a two-stage differential configuration with two integrated inductors for input and interstage matching. For a 72.2Mbit/s, 64-QAM 802.11n OFDM signal at an average and peak output power of 9.4dBm and 17.4dBm, respectively, the measured EVM is 3.8%. The PA meets the spectral mask up to an average output power of 14dBm.
