Why Choose This Product
The 617-2700MHz 3×3 Hybrid Combiner Matrix is engineered to anchor dense In-Building Solutions (IBS) and Distributed Antenna Systems (DAS). Striking a balance between multi-carrier consolidation and system efficiency, it seamlessly routes low-band cellular allocations—including the critical 617-698MHz (Band n71) 5G spectrum—alongside standard mid-band LTE frequencies. With a premium ≤-160dBc PIM profile, it ensures that high-power concurrent transmissions do not generate harmonic interference that could desensitize receiver ports. The matrix architecture distributes power equally across three output paths with excellent port-to-port isolation (≥23dB) and a low VSWR of ≤1.25. Sealed in a robust enclosure with low-PIM 4.3-10 Female interfaces, this 300W unit is optimized for multi-operator co-location environments where signal purity is paramount.

FAQ
- What makes the 617MHz frequency capability unique for this 3×3 coupler?
- Most legacy hybrid combiners cut off at 698MHz. This model is specially engineered to support an extended low-end range down to 617MHz. This ensures full native compatibility with 5G NR Band n71, allowing building owners and operators to integrate ultra-wide-coverage low-band 5G into their shared antenna infrastructure.
- How does a 3×3 hybrid matrix manage signal distribution?
- A 3×3 hybrid matrix accepts up to three independent RF signal sources (such as different base station sectors or different wireless carriers). The internal circuit cross-couples these signals, splitting the combined energy equally across three independent output lines. This guarantees that all three sectors or antennas broadcast all three input networks simultaneously with fixed phase offsets.
- Why is the insertion loss specified near 5dB for a 3×3 configuration?
- By the laws of RF physics, splitting a single signal perfectly three ways splits the power into thirds, resulting in a mandatory theoretical mathematical split loss of 4.77dB per port ($1/3$ power). The specified real-world insertion loss of 5±1.3dB demonstrates an exceptionally efficient architecture, contributing only a fraction of a decibel in true physical trace dissipation.
- What should be done if an installation uses fewer than 3 inputs or 3 outputs?
- To maintain the unit’s rated port-to-port isolation (≥23dB), uncompromised amplitude balance, and low VSWR, any unused input or output port must be terminated with a high-quality 50Ω dummy load. The attached termination load must be rated to match the power levels handled by that specific branch of the matrix.
- Why are 4.3-10 Female connectors preferred over traditional N-type ports?
- The 4.3-10 connector interface is the modern telecommunications industry standard for low-PIM applications. By completely separating the electrical contact plane from the mechanical torque mechanism, it ensures that the critical ≤-160dBc PIM rating remains stable and uncompromised even if connected cables experience physical shifting, stress, or vibration.
