KRYTAR’s Butler matrix family includes 13 models providing operating performance over the 0.5 to 40 GHz frequency range. These Butler matrices rely on KRYTAR’s 90-degree and 180-degree hybrid couplers to provide good phase accuracy, amplitude imbalance, stability and repeatability performance. This family offers phase imbalance values of ±3 to ±15 degrees, amplitude imbalance values of ±0.4 to ±1.6 dB, isolation values of 10 to 16 dB minimum, insertion loss values of 8.0 to 13.5 dB maximum and VSWR values of 1.2:1 to 2.0:1 maximum, depending on frequency range. All models include SMA female or 2.4 mm female connectors for higher frequency performance. KRYTAR also offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications.
A KRYTAR Butler Matrix can be utilized as a beamforming network to feed phased array antenna elements to control RF beamforming and beam steering. The Butler matrix advantage over other beamforming methods is the simplicity of use in a variety of applications. KRYTAR’s Butler matrices target antenna array beamforming in applications like 5G NR, Wi-Fi 6 and Wi-Fi 6E, mmWave, MIMO radio links, radio direction finding, multipath simulation and performance evaluation.
