Description
Precision-engineered for telecommunications infrastructure, this 4×4 hybrid matrix uses an internal network of 3dB hybrid couplers to ensure that every output port receives exactly one-fourth (approx. 6dB loss) of the combined input energy. This design offers superior port-to-port isolation (typically ≥20dB to 25dB), protecting radio equipment from cross-talk and mutual interference. The housing is typically constructed from tri-alloy plated brass or aluminum, ensuring high conductivity and a long operational life in challenging environments.
The device is optimized for low PIM (typically ≤-155dBc to -161dBc), which is essential for maintaining a clean noise floor and maximizing data throughput. With its high power rating, it can easily handle the outputs of multiple high-power base station amplifiers. Its compact and rugged design makes it suitable for integration into both indoor building solutions (IBS) and sheltered outdoor cabinets where high-capacity signal routing is required.
