KRYTAR, Inc. announced four new butler matrix models with broadband frequency coverage from 0.5 to 8.0 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 passive beamforming network solutions to the communications market.

The four new butler matrix models add to the company’s growing list of beamforming products using 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 0.5 to 8.0 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 New Radio, mmWave, MIMO testing, multipath simulation and performance evaluation and many newer applications.
