Abstract
In this study, a transceiver is designed,implemented, and demonstrated by using the Xilinx RFSoC platform and the Python Productivity for Zynq (PYNQ) software framework. Its circuit is particularized for the physical downlink shared downlink channel (PDSCH) of a 5G new radio (NR) link at the FR2 frequency band of 28 GHz. This RFSoC platform is scalable to provide multiple T/R channels for high data rate transmission and can be integrated with the RF subsystem of an active antenna array to format the basic radio unit (RU) of the O-RAN system. The algorithms in the physical layer and corresponding logic circuits are introduced and studied to show the basic behaviors of radio transmission. Radio Frequency (RF) up-/down-converters and millimeter-wave (mmW) antennas are added for the wireless communication test to demonstrate the communication links at 28 GHz, a potential 5G system at mmW frequencies.
