MIcable 2.4-7.25/6-18/18-40/24-43GH 4x4 butler matrix can transfer the signal reciprocally from any of 4 ports to any of other 4 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 multiple microwave bands such as S、C、X、Ku、K and Ka, 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.
