Universal Software Radio Peripheral USRP-LW N321
Product Overview
USRP-LW N321 is a network SDR that provides reliability and fault tolerance for deployment in large-scale and distributed wireless systems. This is a high-performance SDR that provides 2 RX and 2 TX channels in a half-width RU size. Each channel can provide up to 200 MHz instantaneous bandwidth and cover an extended frequency range from 3 MHz to 6 GHz. The baseband processor uses Xilinx Zynq-7100 SoC to deliver a large user-programmable FPGA. It has two SPF+ ports and one QSFP+ port, supports 1 GbE, 10 GbE and Aurora interfaces, and can stream high-throughput IQ to the host PC or FPGA coprocessor. The flexible synchronization architecture supports 10 MHz clock reference, PPS time reference, external TX and RX LO input and GPSDO, which can realize phase coherent MIMO test platform.
