Abstract: A 28 nm CMOS 60 GHz polar transmitter (TX) is presented. It can handle modulations up to 64 QAM with a baudrate up to 1.76 Gbaud. Both amplitude and phase modulation are performed on chip at a sample rate up to 5.28 GS/s. The saturated output power is 12.6 dBm and the peak drain efficiency is 26.0 %. A TX data rate of 10.56 Gb/s is achieved with a DAC alias at ᆧ.4 dBc. With a core area of 0.115mm2 this transmitter consumes 95.4 mW (without on-chip memory) from a 0.9 V supply.
