Abstract :
A 60 GHz-band 2×2 phased-array transmitter with independent tuning of vertical and horizontal polarizations is implemented in 65 nm bulk CMOS. Two-dimensional phase tuning via LO phase shifting is implemented in a transmitter that adopts zero-IF upconversion with dynamic DC biasing to minimize LO feedthrough. The 2.9×1.4 mm2 chip consumes a total of 590 mW from a 1 V supply when driving all 4 channels at a maximum saturated output of 11 dBm with 20 dB gain per transmitter.
