The KBM9100400 is a 4×4 Butler matrix designed for beamforming in phased array antenna systems operating from 10 to 40 GHz. It features 2.4 mm female connectors, a maximum phase imbalance of ±15 degrees, a maximum amplitude imbalance of ±1.2 dB, insertion loss less than 12 dB, maximum VSWR of 2:1, and minimum isolation of 12 dB. The unit measures 3.68 inches in length, 2.80 inches in width, and 0.81 inches in height. The phase relationships between inputs and outputs follow a predefined matrix with values of 0°, 90°, 180°, and -90°.
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 KBM9100400, 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.
KRYTAR’s technological advances provide excellent operating performance of this new 4×4 Butler Matrix. Covering the frequency range from 10.0 to 40.0 GHz this Butler Matrix provides ±1.2 dB of maximum Amplitude Imbalance and maximum Phase Imbalance of ±15 degrees. This Butler Matrix exhibits Insertion Loss of < 12 dB with Maximum Input and Output VSWR of 2.0:1 dB and Isolation of 12 dB. Average Power rating is 20 watts.
Model KBM9100400 Butler Matrix is a compact package measuring just 3.68 inches (L) x 2.80 inches (W) x 0.81 inches (H), and comes with standard 2.4mm coaxial female connectors.
