Abstract
This paper presents a 39GHz 64-element phased-array transceiver based on 4-element transceiver chipset with LO phase shifting architecture and built-in gain phase calibration. A phase-to-digital-convertor (PDC) and a high-resolution phase detection mechanism are proposed. The built-in calibration has an measured accuracy of 0.08-degree RMS phase error and 0.01-dB RMS gain error. The LO phase shifting based transceiver has a 0.04-dB maximum gain variation over the 360◦ full tuning range. The proposed pseudo-single-balanced mixer realizes -70 dBm LO-feedthrough (LOFT) cancellation and maximum 0.5° LO-to-LO isolation. The 8TX-8RX phased-array transceiver module 1-m OTA measurement supports 5G new radio (NR) 400MHz 256QAM OFDMA modulation with -30.0dB EVM. The 64-element transceiver has a EIRP MAX of 53dBm. The 4-element chip consumes a power of 1.5W in TX mode and 0.5W in RX mode.
