Abstract :
A 60GHz RF-combining phased-array front-end is implemented in silicon using a hybrid parallel/series phase-shift approach that reduces the requirements of the on-chip phase shifters. The 4-element array provides for simultaneous illumination of 2 angles of incidence and includes amplitude control and continuous phase adjustment. The front-end NF <6.9dB at 60GHz and the array achieves full spatial coverage with peak-to-null ratio >25dB. It consumes 265mW and occupies 4.6mm2.
