The 8401-8-5 from Spectrum Control is an 8x8 Butler Matrix that operates from 0.7 to 6 GHz. It can handle an input power of 5 W (~37 dBm), has an insertion loss of less than 16 dB, and provides a port-to-port isolation of 20 dB. This butler matrix is designed to transfer a signal reciprocally from any of the eight input ports to any of the eight output ports with an output phase accuracy of ±20° (at 5 GHz). It is available in a module that measures 152.4 x 103.7 x 16.7 cm and has SMA-female connectors. The butler matrix is ideal for use in Wi-Fi, WiMAX, 4G/5G testing, antenna array beamforming, interferometer system simulation and testing, multipath simulation and performance evaluation, and MIMO testing applications.
