Butler
Matrix
Passive beamforming networks that produce fixed spatial beams with defined phase progressions — enabling directional antenna testing without active electronics, calibration overhead, or complex control systems.
Available in 4×4 and 8×8 configurations across two frequency bands — all models are fully passive, bidirectional, and built with 50 Ω SMA interfaces for seamless integration into any RF test setup.

Key Features
Precision passive beamforming
Fixed Beam Patterns
Each input port activates a distinct, repeatable spatial beam — no active control needed.
Passive & Bidirectional
Fully passive network supporting bidirectional RF operation, ideal for test environments.
Defined Phase Offsets
Precise phase progression across antenna outputs enables accurate beam direction simulation.
Uniform Amplitude
Equal-amplitude outputs ensure consistent signal levels across all antenna ports.
Broadband Coverage
Wide frequency range supports 5G FR1, Wi-Fi 6/6E/7, and other multi-standard tests.
Compact & Rugged
Slim 10 mm form factor fits lab racks and field systems without additional hardware.
