In this paper, a wirelessly-powered 28-GHz phased-array relay transceiver for 5G network is proposed. This relay transceiver consists of the proposed vector-summing backscatter for Tx and passive phase-shifting self-heterodyne receiver and rectifier for Rx and 24-GHz WPT. This transceiver implemented with on-PCB array antennas achieves -27.5dB and -31.3dB EVM for Tx and Rx for a 400-MHz 64QAM OFDMA-mode signal (5G NR, MCS 19) without any wired power supply.
