Towards wide bandwidth and high output power density for 60GHz PA design in 65nm CMOS, this paper introduces a 2D differential power combining network by metamaterial-based zero-phase-shifter. Simultaneous distributed amplification and power combining can be achieved with improved performances in both power density and bandwidth. The PA measurement results show 13.2 dB gain, 8.7% PAE, 13dBm P1dB, and 20GHz bandwidth (53 to 73GHz) within an area of 0.268mm2.
