Abstract: Emerging wireless applications such as 5G cellular, large intelligentsurfaces (LIS), and holographic massive MIMO require antenna array processingat mm-wave frequencies with large numbers of independent digital transceivers.This paper summarizes the authors recent progress on the design and testing of28 GHz and 60 GHz fully-digital array processing platforms based on widebandreconfigurable FPGA-based software-defined radios (SDRs). The digital basebandand microwave interfacing aspects of the SDRs are implemented on single-chip RFsystem-on-chip (RF-SoC) processors from Xilinx. Two versions of the RF-SoCtechnology (ZCU-111 and ZCU-1275) were used to implement fully-digitalreal-time array processors at 28~GHz (realizing 4 parallel beams with 0.8 GHzbandwidth per beam) and 60~GHz (realizing 4 parallel beams with 1.8~GHzbandwidth per beam). Dielectric lenslet arrays fed by a digital phased-arrayfeed (PAF) located on the focal plane are proposed for further increasingantenna array gain.
