The processing requirements of 5G-NR are much higher than those of 4G, thus requiring high-performance SDR devices or even more advanced PCs as the host computer for USRP. Through the accompanying millimeter-wave expansion module and up-converter, continuous frequency conversion from 24GHz to 44GHz can be supported, meeting the research needs of 5G millimeter-wave communication.

(1) SDR-LW Series
The SDR-LW series is a high-performance SDR standalone device launched by Luoguang Electronics. It consists of an onboard processor, FPGA, and RF front-end. By working in synergy with the Intel X86 processor and FPGA, the flexibility of software-defined radio equipment is enhanced. The host of the SDR-LW series device can run 5G base station/terminal software, and the front-end realizes signal transmission for base stations and terminal devices through horn antennas. The integrated design framework enables it to quickly build prototypes of high-performance mobile wireless communication systems. It is recommended to choose the SDR-LW 2974 and SDR-LW 3980 models:

(2) USRP-LW Series
USRP-LW N321 is a high-performance software-defined radio device featuring an instantaneous bandwidth of up to 200 MHz RF front-end, supporting MIMO configuration, and equipped with high-speed ADC and DAC. It can handle complex signal processing tasks and meet diverse wireless communication requirements. Soft base stations and soft terminals are set up on the PC connected to USRP-LW N321 to implement NR wireless protocol stack functions. USRP-LW N321 completes digital-to-analog conversion and completes the transmit and receive functions at the RF end.

The baseband processor of USRP-LW N321 adopts Xilinx Zynq-7100 SoC, integrating a large-scale user-programmable FPGA and dual-core ARM CPU, providing strong support for real-time and low-latency processing. By using SFP+ and QSFP+ ports, USRP-LW N321 can transmit high-throughput I/Q data streams to the host PC or FPGA coprocessor, meeting the requirements of high-speed data processing. It supports remote execution tasks, such as software update, restart, and factory reset, thereby simplifying the control and management of the radio network.
