The 8401 Series butler matrix is a high performance 4x4 butler matrix, covering several frequency bands from 0.5 to 8GHz. It can transfer the signal reciprocally from any of 4 inputs ports to any of other 4 output ports, with high phase accuracy, amplitude balance, low insertion loss, and high port-to-port isolation.
Features• Compact, modular microstrip design and construction
• Phase shift is nominally balanced for equal phase shift over both frequency bands
• Custom frequency ranges and configurations are available. Please consult the factory
