A Butler matrix is a beamforming network used to feed a phased array of antenna elements. Its purpose is to control the direction of a beam, or beams, of radio transmission.
KRYTAR’s Butler Matrix can be utilized as a beamforming network used to feed a phased array of antenna elements with the purpose to control the direction of a beam, or beams, of radio transmission. The advantage over other methods of angular beamforming is the simplicity of use in a variety of applications. KRYTAR’s 4×4 Butler Matrix, Model KBM9005010, is the ideal choice for antenna array beamforming, 5G NR (New Radio), Wi-Fi 6 and Wi-Fi 6E, mmWave, MIMO testing, multipath simulation and performance evaluation, and many other upcoming applications.
Covering the frequency range from 0.5 to 1.0 GHz this Butler Matrix provides ±0.4 dB of maximum Amplitude Imbalance and maximum Phase Imbalance of ±3 degrees. This Butler Matrix exhibits Insertion Loss of 8.0 dB with Maximum Input and Output VSWR of 1.3:1 dB and Isolation of 16 dB. Average Power rating is 20 watts.
Model KBM9005010 Butler Matrix is a compact package measuring just 11.95 inches (L) x 4.80 inches (W) x 1.35 inches (H), and comes with standard SMA coaxial female connectors.
