KRYTAR Announces Three New 4x4 BUTLER Matrices

Three 4x4 BUTLER Matrices

January 3, 2023

KRYTAR, Inc., a leader in the design and production of ultra-broadband microwave components and test equipment, announces three new 4x4 BUTLER matrices with ultra-broadband frequency coverage from 1.0 to 40.0 GHz. 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 long history of excellence in the design of broadband microwave components affords the ability to produce unique ultra-broadband passive beamforming network solutions to the communications market.

The three New 4x4 Butler Matrix models use KRYTAR’s high performance 90- and 180-degree hybrid couplers providing super phase accuracy, amplitude imbalance, stability and repeatability. Offering coverage of multiple microwave bands, from 1 to 40 GHz, a KRYTAR Butler Matrix offers superior electrical performance in a single ruggedized package and is the ideal choice for a wide range of applications including antenna array beamforming, Wi-Fi 6 and Wi-Fi 6E, 5G NR (New Radio), mmWave, MIMO testing, multipath simulation and performance evaluation and many newer applications.

Model KBM9010180 covers the frequency range from 1.0 to 18.0 GHz and provides ±1.0 dB of maximum amplitude imbalance and maximum phase imbalance of ±18 degrees. This Butler Matrix exhibits low insertion loss of 12.0 dB with low VSWR of 1.7:1 dB and High Isolation of 14 dB.  This Butler Matrix is a compact package measuring just 3.68 (L) x 2.80 (W) x 0.81 in. (H) and comes with standard SMA coaxial female connectors.

Model KBM9014265 covers the ultra-wideband frequency range from 1.4 to 26.5 GHz this Butler Matrix provides ±1.6 dB of maximum amplitude imbalance and maximum phase imbalance of ±17 degrees. This Butler Matrix exhibits Low insertion loss of 13.5 dB with low VSWR of 2.0:1 dB and High Isolation of 10 dB. This Butler Matrix is a compact package measuring just 4.78 (L) x 3.71 (W) x 1.11 in. (H) and comes with standard SMA coaxial female connectors.

Model KBM9100400 covers the ultra-wideband frequency range from 10.0 to 40.0 GHz and provides ±1.2 dB of maximum amplitude imbalance and maximum phase imbalance of ±15 degrees. This model exhibits low insertionloss of 12.0 dB with low VSWR of 2.0:1 dB and high isolation of 12 dB. This Butler Matrix is a compact package measuring just 3.68 (L) x 2.80 (W) x 0.81 (H) in. and comes with standard 2.4 mm coaxial female connectors.
