摘要

This article presents a 71–86 GHz 16-element array receiver application-specified integrated circuit (ASIC) for Massive multiple-input–multiple-output (MIMO) wireless uplink, featuring a multiple-output analog beamformer (BF) supporting up to 16 spatially multiplexed users at the same time. The ASIC includes 16 direct-conversion mixer-first RX front-ends, local oscillator (LO) generation and distr...
