Description
Constructed for carrier-grade reliability, this 4×2 hybrid matrix uses precision internal circuitry to ensure that each output port receives a combined version of all four inputs. This design offers superior port-to-port isolation (typically ≥20dB to 23dB), which is critical for preventing cross-talk between different radio sectors or operators. The housing is typically made from tri-alloy plated aluminum or brass, providing excellent electrical conductivity and resistance to environmental corrosion.
The device is optimized for low PIM (typically ≤-153dBc to -161dBc), ensuring that the noise floor remains low even under high-power multi-carrier loads. This is essential for maintaining the high data throughput required by modern cellular standards. Most models feature N-Female connectors and are housed in rugged, compact enclosures suitable for both indoor head-end racks and sheltered outdoor cabinets.
