Description
8401E Butler Matrix — 4×4 (2.4–7.25 GHz)
The 8401E is a 4×4 Butler matrix — a beamforming network used in wireless test applications (cellular, WiFi, Bluetooth). It transfers signals reciprocally from any input port to any output port with high phase accuracy, amplitude balance, low insertion loss, and high port-to-port isolation. Its compact, modular microstrip construction makes it ideal for MIMO test setups across 5G, WiFi, and WiMAX.
Key Features
- Compact, modular microstrip design and construction
- Reciprocal signal path
- Excellent channel condition number
- Technology agnostic
- Wide frequency range
