A 24-to-30GHz 256-Element Dual-Polarized 5G Phased Array with Fast Beam-Switching Support for >30,000 Beams

Abstract

In Paper 27.3, IBM T.J. Watson Research Center and Fujikura demonstrate a 24-to-30GHz 256-Element dual-polarized 5G phased array with fast beam-switching support for >30,000 beams enabled by an on-chip beam calculator with 200ns beam-setup and 8ns OTA-switching time. This 22-to-30GHz BF-IC provides coverage for n257/n258/n261 5G NR bands with 64- and 256-element peak PAE of 20% and <4dB receiver NF.
