A 60GHz Phased Array in CMOS

This work comprises an array of 4 phase shifters and antennas operating at 60GHz for a beamforming system. Pass gates form the switching core for a phase selector circuit which is replicated to build up a vector modulator phase shifter. The final beam accuracy is better than 2deg for a 16-way system. The die area is 2.7mm times 2.8mm, the buffers take 240mA from a 1.2V supply, the pass gates take no power
