A polar TX based on a 10GSample/s RF-DAC aimed at 802.11ad applications realizes more than 30dB alias attenuation and exceeds 3GHz input bandwidth with 6x oversampling factor. The PA drain efficiency is 29.8% with a Psat of 10.8dBm. Average TX output power is 5.3dBm with 15.3% PA efficiency running QPSK at 3.3Gb/s datarate and -23.6dB EVM. Corresponding 16-QAM values are: 3.6dBm with 11.6% at 6.7Gb/s and -18.1dB EVM. The 0.18mm2 TX core in 40nm bulk-CMOS consumes 40.2mW from 0.9V.
