A 50mW-TX 65mW-RX 60GHz 4-element phased-array transceiver with integrated antennas in 65nm CMOS

Abstract

The 60GHz band has gained great interest as an enabler for multi-Gb/s wireless links. Recent efforts [1-4] have focused on reducing transceiver power to drive adoption of 60GHz in mobile devices. To further accelerate this adoption, the cost of current mm-Wave solutions should also be reduced. Especially for short range designs (<;1m), overall cost may be dominated by packaging and testing. This paper therefore presents a low-power 60GHz CMOS 4-element phased-array QPSK transceiver with integrated slot-loop antennas. Utilizing such antennas as well as circuit stacking techniques, the transceiver achieves 10.4Gb/s with a range of >40cm in all directions while consuming only 115mW (TX+RX).
