Description
Constructed for infrastructure-grade durability, this 4-way combiner is often built with a brass or aluminum body and tri-alloy plated connectors to ensure superior conductivity and environmental protection. Its wideband design allows for the seamless integration of signals across the entire sub-3GHz spectrum. To maintain high signal integrity, the internal circuitry is designed to provide high port-to-port isolation (typically ≥20dB), preventing mutual interference between the four input radios.
Many professional-grade 4:1 combiners are optimized for low Passive Intermodulation (PIM), which is critical for preventing receiver noise and maintaining peak data speeds in 4G and 5G networks. These units are typically designed to handle significant average power (often 20W to 300W depending on the specific model) and are housed in rugged, compact enclosures suitable for mounting in equipment racks or wall-mounted IBS cabinets.
Key Technical Advantages
-
Consolidated Signal Path: Merges four separate inputs into one output, significantly reducing the amount of cabling and hardware needed for antenna distribution.
-
Broad Frequency Support: Covers the complete 698MHz to 2700MHz range, supporting all major global 3G, 4G, and early 5G bands.
-
