Frequently Asked Questions
- Q1: What is the primary function of a 3x3 hybrid coupler?
- A: A 3x3 hybrid coupler is used to combine three independent signal sources and distribute them equally among three output ports. This is essential for neutralizing multi-operator interference in neutral-host DAS environments.
- Q2: Why is the -160dBc PIM rating significant for this model?
- A: An ultra-low PIM of ≤-160dBc is critical for modern high-speed data networks. It ensures that the combining process does not generate intermodulation products that could degrade system sensitivity and lower network capacity.
- Q3: What are the advantages of using 4.3-10 connectors?
- A: 4.3-10 connectors offer superior PIM performance and a smaller footprint compared to traditional 7/16 DIN connectors. They also allow for more reliable connections with lower torque requirements, making them the standard for 5G-ready infrastructure.
- Q4: Can this device handle high-power signals from multiple base stations?
- A: Yes, with a power handling capacity of 300W per port, this hybrid coupler is robust enough to manage high-power inputs from various BTS units simultaneously.
- Q5: Is this hybrid coupler suitable for outdoor installation?
- A: Absolutely. It features an IP65 rating, providing excellent protection against dust and water, ensuring reliable long-term performance in both indoor and harsh outdoor environments.
