ETTUS USRP X440 Compible USRP SDR, 8 Channel, Phase-Coherent, Xilinx Zynq UltraScale+ MPSoC, USRP Software Defined Radio Device

Developed entirely by Wuhan Luowave Electronics, the Luowave LW820 represents a cutting-edge 8-channel coherent SDR solution, integrating ADI's ADRV9009 RF transceiver and Xilinx UltraScale+ ZU11EG SoC for superior signal processing performance. Operating across 75 MHz to 6 GHz with 200 MHz instantaneous bandwidth per channel, this platform ensures ultra-low phase deviation (<1°) across multiple units, making it ideal for 5G/6G, radar, satcom, and spectrum sensing applications.

Phase Synchronization Test

The Luowave LW820 contains 4 pieces of ADRV9009. It not only has a multi-chip phase synchronization mechanism but also integrates a digital calibration function, which can perform phase calibration on the internal circuits. This further optimizes the phase synchronization performance. In scenarios where multiple chips work collaboratively and complex signal processing is involved, the Luowave LW820 can stably and accurately maintain phase synchronization, meeting the stringent application requirements for phase synchronization in 5G communication, radar detection, etc., and effectively enhancing the overall system performance. The phase synchronization consistency deviation can reach 1°.
