KRYTAR, Inc announces a new 4×4 Butler matrix with broadband frequency coverage from 2.4 to 7.25 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 broadband passive beamforming network solutions to the wireless communications market.
The New 4X4 Butler Matrix, Model KBM90240725, use KRYTAR’s own high performance 90- and 180-degree hybrid couplers providing super phase accuracy, amplitude imbalance, stability and repeatability. Offering coverage from 2.4 to 7.25 GHz, this KRYTAR Butler matrix offers superior electrical performance in a single ruggedized package. It is the ideal choice for antenna array beamforming, 5G NR (New Radio), Wi-Fi 6 and Wi-Fi 6E, mmWave, MIMO radio links, multi-path simulation and performance evaluation and many other upcoming applications operating within the higher frequency bands.
KRYTAR’s technological advances provide excellent operating performance of this new Model KBM90240725 4X4 Butler matrix. Covering the frequency range from 2.4 to 7.25.0 GHz (S- and C-Bands) this Butler matrix provides ±0.8 dB of maximum amplitude imbalance and maximum phase imbalance of ±8.9 degrees. This Butler matrix exhibits insertion loss of <7.9 dB with maximum input and output VSWR of 1.5:1 dB and isolation of 14 dB and average power rating is 20 W.
Model KBM90240725 Butler matrix is a compact package measuring just 4.75 (L) x 3.46 (W) x 1.11 (H) in., and comes with standard SMA female coaxial connectors.
KRYTAR’s 4×4 Butler matrix family uses KRYTAR’s high performance 90- and 180-degree hybrid couplers offering coverage of multiple microwave bands, from 0.5 to 40 GHz providing super phase accuracy, amplitude imbalance, stability and repeatability each within a single compact package with coaxial connectors.
