16×16 Butler Matrix supports MIMO beamforming tests

Spectrum Control has introduced the Weinschel™ 8401-16E 16×16 Butler Matrix, a passive beamforming network for MIMO systems and wireless test applications across 2.4 GHz to 7.125 GHz. The 16-input, 16-output architecture generates fixed orthogonal beams without active phase shifters, supporting repeatable beamforming, multi-channel validation and simulated OTA testing for Wi-Fi 6E, Wi-Fi 7 and…
