MIcable 0.617~7.25GHz 4x4 & 8×8 butler matrices can transfer the signal reciprocally from any of 4 or 8 ports to any of other 4 or 8 ports. Because the high performance passive components and cables are used inside, the system has super phase accuracy, amplitude balance, stability and repeatability. They cover the world's mainstream 5G NR(FR1)，WIFI 6E bands，making them an ideal choice for 5G testing, WIFI 6E testing, MIMO testing, multipath simulation and performance evaluation, antenna array beam-forming and other applications.
