N2 - This paper presents a wideband channelized phased array receiver that uses sub-harmonic injection locked oscillators. The combination of channelization and sub-harmonic injection locking synchronizes the center of the sub-bands so beam squinting is reduced by the number of bands. Channelization additionally, reduces the performance requirements for the ADCs by reducing their speed requirement and also by reducing the SNR requirements due to a reduction in PAPR. The two-band prototype design realized in 65nm GP CMOS is centered at 9GHz, provides 4GHz instantaneous bandwidth, reduces beam-squinting by half (i.e., for 2 channels), consumes 31.75mW/antenna and occupies 2.7mm2 of chip area.
