A low-power radio chipset in 40nm LP CMOS with beamforming for 60GHz high-data-rate wireless communication

The link budget of multi-Gb/s wireless communication systems around 60GHz improves by beamforming. CMOS realizations for this type of communication are mostly limited to either one-antenna systems [1], or beamforming ICs that do not implement all radio functions [2]. The sliding-IF architecture of [3] uses RF phase shifting, which deteriorates noise performance.
