The KBM9010180 from KRYTAR is a 4x4 Butler Matrix that operates from 1 to 18 GHz. It has a phase imbalance of ±18° and an amplitude imbalance of ±1 dB. This butler matrix provides more than 14 dB of isolation and has an insertion loss of 12 dB. It is available in a module that measures 5.87 x 4.80 x 1.35 inches with SMA-female connectors. 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. It can be used for a wide range of applications including antenna array beamforming, Wi-Fi 6 and Wi-Fi 6E, 5G NR (New Radio), MIMO testing, multipath simulation, performance evaluation, and many newer applications.
