8401-8 8x8 Butler Matrix

A Weinschel Product

APITech’s 8401-8 Series is a high performance 8x8 butler matrix, covering several frequency bands from 0.5 to 8GHz. The 8401-8 unit is optimized for the 2.4 to 2.5 GHz and 4.8 to 6.0 GHz frequency bands, while the 8401-8E unit is optimized for the 2.4 to 2.5 GHz and 4.8 to 7.25 GHz frequency bands. The Butler matrix can transfer the signal reciprocally from any of 8 inputs ports to any of other 8 output ports, with high phase accuracy, amplitude balance, low insertion loss, and high port-to-port isolation.
