Weinschel Butler Matrix beamforming networks

The Butler Matrix family of beamforming networks, from Weinschel by Spectrum Control, have been designed for use in wireless test applications.

Suitable for RF MIMO testing over a large frequency range for transceiver and receiver applications, the beamforming networks reciprocally transfer signals from any of the input ports to any of the output ports, with high phase-accuracy, amplitude balance, low insertion loss and high port-to-port isolation. In transmitting mode, they are designed to deliver maximum power, with progressive phase shift to the output. In receiving mode, they collect signals from all beam directions with the full gain of antenna array.

The range includes the 8401, 8401-8 and 8401-16 models, which can be used in a variety of configurations across cellular, Wi-Fi and any band within their frequency limits.
