APITech's 8401 series is a high performance 4x4 Butler matrix, covering several frequency bands from 500 MHz up to 8GHz. It can transfer the signal reciprocally from any of 4 input ports to any of other 4 output ports, with high phase accuracy, amplitude balance, very small insertion loss and high port to port isolation. The unit has very stable, repeatable performance.
