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 bo...
