Product Description
This high-performance Quad Unit RF Combiner is a specialized modular solution designed for complex multi-band network integration. It features ultra-low PIM (≤-160dBc) and high isolation (≥65dB) between ports to ensure minimal signal interference. With its robust IP68 waterproof rating, it is perfectly suited for both indoor and extreme outdoor applications. Equipped with 4.3-10 type female connectors, it supports DC pass on all ports, providing maximum flexibility for tower-mounted equipment.

Frequently Asked Questions
- Q1: What are the advantages of the Quad Unit modularity?
- The Quad unit design allows for high-density integration of multiple frequency paths into a single housing. This reduces the overall footprint on the tower, simplifies cable management, and lowers installation costs for multi-operator sites.
- Q2: How does the IP68 rating compare to standard outdoor equipment?
- An IP68 rating is one of the highest levels of environmental protection. It ensures the combiner is completely dust-tight and can withstand continuous immersion in water, making it reliable for extreme weather conditions.
- Q3: Does this combiner support active equipment power supply?
- Yes, it features DC pass on all ports. This enables the base station to power active devices like Tower Mounted Amplifiers (TMAs) directly through the RF feeder line without needing additional external power cables.
- Q4: Why is the isolation level critical for these specific frequencies?
- With isolation ≥65dB, the device effectively prevents cross-talk between the 2575-2615MHz and 2540-2680MHz bands. This is essential for maintaining high signal sensitivity and preventing interference in co-located network environments.
