Butler Matrices
Spectrum Control's Weinschel brand Butler Matrices are beamforming network modules that transfer signals reciprocally from any number of input ports to output ports, with high phase accuracy, amplitude balance, low insertion loss, and high port-to-port isolation.
Ideal for test environments, they deliver maximum power with progressive phase shift to the output in the transmitting mode, and collect signals from all beam directions with the full gain of antenna array in the receiving mode. Frequency range options include 2.4 - 7.2 GHz and 0.5 - 6 GHz.
