A 60-GHz 8-Way Phased-Array Front-End With T/R Switching and Calibration-Free Beamsteering in 28-nm CMOS.

An eight-way phased-array TRX front-end with RF phase shifting and on-chip transmit/receive switching is implemented in 28-nm CMOS. The TX P1dBout and RX noise figure (NF) are 10 dBm and 6.8 dB, respectively. The active phase shifter shows less than 5° phase resolution and amplitude errors within ± 0.35 dB. The 9.6-mm2chip consumes 231 mW in RX and 508 mW in the TX mode from a 0.9-V supply. When c...
