Key Product Highlights & Selection Guide

Product CategorySelection Parameters/Specifications
Butler Matrices & Beamforming NetworksLook for matrix size (i.e. ports), phase accuracy and insertion loss. Available in standard configurations like 4x4, 8x8, 16x16, and up to 64x64.
Power Dividers and CombinersSelect way count as per need. Ranging from 2-way up to 32-way (or custom N-way) splits. The other parameters are bandwidth and amplitude/phase balance. Strict amplitude (e.g., +/- 0.2 dB) and phase balance are strictly required for coherent signal processing.
Directional Couplers & Hybrid CouplersHybrid Type (90-degree, 180-degree), Directivity, coupling value
Antennas (Spiral, Horn, and Arrays)Polarization ( linear, circular, or dual-polarized options, Gain & Beamwidth)
