4×4 Butler Matrix: KBM9020060
The new KRYTAR 4×4 Butler Matrix uses KRYTAR’s high-performance 90- and 180-degree Hybrid Couplers providing super phase accuracy, amplitude imbalance, stability and repeatability.
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 KBM9020060, is the ideal choice for antenna array beamforming, 5G NR (New Radio), Wi-Fi 6 and Wi-Fi 6E, mmWave, MIMO (Multiple-Input and Multiple-Output) radio links, multipath simulation and performance evaluation, and many other upcoming applications.
Covering the frequency range from 2.0 to 6.0 GHz this Butler Matrix provides ±1.0 dB of maximum Amplitude Imbalance and maximum Phase Imbalance of ±8 degrees. This Butler Matrix exhibits Insertion Loss of 7.5 dB with Maximum Input and Output VSWR of 1.4:1 dB and Isolation of 14 dB. Average Power rating is 20 watts.
Model KBM9020060 Butler Matrix is a compact package measuring just 4.75 inches (L) x 3.46 inches (W) x 1.11 inches (H), and comes with standard SMA coaxial female connectors.
