2026-06-15 Hardware Design of a Highly Integrated RFSoC-Based Platform for Wideband Spectrum Sensing doi:10.57760/sciencedb.39877 en Wideband spectrum sensing demands receiving front-ends with wide instantaneous bandwidth and high integration density, posing significant system-level hardware design challenges. This paper presents the system-level hardware design of a highly integrated, single-board software-defined radio (SDR) platform built around the Xilinx XCZU27DR Radio Frequency System-on-Chip (RFSoC). The platform integrates gigasample-per-second (Gsps) data converters, FPGA programmable logic, multi-core ARM processors, 2 GB of DDR4 memory, and diverse high-speed peripheral interfaces onto a single board measuring 150 mm by 100 mm. Key design strategies are detailed, including a hierarchical power supply scheme that employs DC-DC converters for digital circuits and low-dropout regulators (LDOs) for noise-sensitive analog circuits; a low-jitter clock synthesis module based on the LMK04832 that preserves ADC dynamic performance at Gsps sampling rates; and an RF front-end that uses a balun transformer for impedance matching and single-ended-to-differential conversion at the integrated RF-ADC input. The platform adopts a heterogeneous computing architecture combining the processing system (PS) and programmable logic (PL), supporting both distributed and standalone processing modes. The proposed design offers a highly integrated hardware solution for wideband spectrum sensing and other SDR applications.
