Frequently Asked Questions
- Q1: What makes the -160dBc PIM rating significant for this model?
- A: An ultra-low PIM of ≤-160dBc ensures virtually zero signal interference. This is vital for modern high-speed 4G LTE and 5G networks where maintaining a high Signal-to-Noise Ratio (SNR) is essential for maximum data throughput.
- Q2: Can this directional coupler be installed in outdoor environments?
- A: Yes, with its IP65-rated enclosure, it is fully protected against dust and low-pressure water jets, making it reliable for both indoor building solutions and outdoor DAS or BTS deployments.
- Q3: How does the coupling accuracy of ±0.8dB benefit network engineers?
- A: High Coupling Accuracy allows for precise signal management across the DAS network. It ensures that signal levels delivered to each antenna are consistent with the original system design, preventing "dead zones" or over-saturated areas.
- Q4: Why choose an N-Female connector for a 200W rating?
- A: The N-Female connector is a standard in high-power RF applications. It provides excellent mechanical stability and electrical performance, safely handling up to 200W of average power while maintaining a low VSWR.
- Q5: Which cellular bands does this coupler support?
- A: It covers a wide band from 698MHz to 2700MHz, providing full support for 700/800/900MHz (low bands) as well as 1800/2100/2600MHz (high bands), covering virtually all global 2G, 3G, and 4G LTE frequencies.
