Product Overview
The Triple Band Combiner (Triplexer) is a high-performance passive device designed to combine or split three distinct frequency bands (790-960MHz, 1710-1880MHz, and 1920-2170MHz) into a single feeder system. Engineered for high-capacity sites, it features Low PIM (-153dBc) and high isolation to ensure minimal interference. With its IP65 waterproof rating and modular design (available in Single or Double configurations), it is perfectly suited for both indoor and outdoor co-siting applications.

Frequently Asked Questions
- Q1: What is the primary advantage of using a Triple Band Combiner?
- A: A Triple Band Combiner (Triplexer) allows operators to combine three different frequency bands into a single output cable. This significantly reduces the number of feeder lines required on a tower, lowering installation costs and wind loading on poles.
- Q2: How does the Low PIM (-153dBc) rating benefit network performance?
- A: Low Passive Intermodulation (PIM) is crucial for high-speed data networks like 4G LTE and 5G. A rating of -153dBc minimizes background noise and interference, ensuring better call quality, higher data throughput, and fewer dropped calls.
- Q3: What is the "DC Pass" feature used for?
- A: The 3A DC Pass capability allows the combiner to transmit direct current power through the RF line. This is essential for powering Tower Mounted Amplifiers (TMAs) or Remote Radio Units (RRUs) directly through the feeder cable.
- Q4: Is this combiner reliable for long-term outdoor use?
- A: Absolutely. With an IP65 waterproof grade and a robust mechanical design, this unit is protected against dust and low-pressure water jets, making it suitable for rooftops and tower-top installations in various climates.
- Q5: Can I request a Double configuration or a different connector type?
- A: Yes. We offer modularity in both Single and Double units to fit different site requirements. We also provide professional OEM services if you need 4.3-10 connectors or customized frequency bands.
