Calibrating a 4-channel Fully-Digital 60 GHz SDR

Published: 21 September 2020 Publication History

Abstract

The Pi-Radio v1 software-defined radio (SDR) features a 4-channel fully-digital transceiver board operating in the 57-64 GHz band; when mated with the Xilinx RFSoC-based ZCU111 board, this forms a powerful SDR that can be used by the research community. This paper describes the calibration procedures for the SDR, with a special emphasis on not relying on expensive laboratory equipment / infrastructure like a spectrum analyzer, signal generator, or even an anechoic chamber. We hope this is an interesting read for those interested in the pipeline from hardware design schematic to fully functional SDR.
