multi-Gb/s wireless communication. Practical mm-Wave systems will require relatively large phased arrays in order to robustly overcome path-loss and fading issues. Despite significant progress [1,2], CMOS implementations of 60GHz phased arrays have so far been area and power hungry. This paper therefore presents a 60GHz 4-element 65nm CMOS phased-array transceiver consuming <34mW/element (including LO synthesis and distribution) that utilizes baseband (BB) phase shifting and holistic impedance optimization. While all phased-array architectures require some form of mm-Wave combining or splitting, phase shifters at RF tend to be large and can introduce substantial losses on either the RF or LO signal paths. On the other hand, phase shifting at BB can achieve improved phase-shifting resolution as well as much lower loss
