A CMOS PA integrating a power detector for all IEEE 802.15.3c bands is demonstrated. A fully synchronous power combiner removes design trade-offs between transformer efficiency and power combining efficiency. At 1 V supply, the measured Psat, OP1dB, and peak PAE at 61.5 GHz are 17.9 dBm, 15.4 dBm, and 11.7% respectively. A Psat of +17 dBm and an OP1dB of +14 dBm are achieved across the 57-to-65 GHz band.
