Butler Matrix drives Wi-Fi and other phased-array antennas

Experience the power of steering signal beams with this innovative passive device designed for over-the-air wireless test systems.

Butler MatrixVaunix Technology introduces the LBM-7250-4 Lab Brick Butler Matrix, a cutting-edge beamforming tool that seamlessly works with phased-array antennas to precisely steer beams between transmitters and receivers. With four passive inputs and outputs, this Butler Matrix is ideal for testing both transmitters and receivers across a frequency range from 2.4 GHz to 7.25 GHz, encompassing Wi-Fi bands, Bluetooth, and 5G cellular networks including CBRS.

Key specifications include:

  • Impedance: 50 Ω
  • Insertion loss: 8 dB (typ), 10.5 dB (max)
  • Phase accuracy: 5° (3.4 GHz to 2.5 GHz); 7 dB (5.15 GHz to 5.85 GHz); 9 dB (5.925 GHz to 7.125 GHz)
  • VSWR: 1.5:1
  • Isolation: 15 dB
  • Maximum input level: 50 W peak
  • Price: $2399.

The LBM-7250-4 Lab Brick Butler Matrix is specifically crafted for antenna, amplifier, and RF system testing, offering the flexibility to integrate multiple modules into a rack for streamlined automated testing processes. Alongside the Butler Matrix, Vaunix also provides a range of USB-controlled active devices like digital attenuators, signal generators, RF switches, and phase shifters, as well as passive devices such as splitters/combiners. Additionally, the company offers Digital Attenuator Handover Test Systems.
