Frequently Asked Questions
- Q1: Why are these couplers ideal for Public Safety DAS?
- Public safety networks require extreme reliability. These couplers provide high isolation and IP65 protection, ensuring that emergency communication signals remain stable and interference-free, even in demanding environments.
- Q2: How does the power handling capability benefit the system?
- With support for up to 300W average power, these directional couplers can handle high-capacity signal loads without overheating or degrading, making them suitable for high-power base stations and distributed antenna networks.
- Q3: What is the significance of Low VSWR in this series?
- A Low VSWR (≤1.35) indicates highly efficient signal transmission with minimal reflection. This ensures that most of the power is delivered to the intended ports, protecting the transmitter and maintaining high system efficiency.
- Q4: Can I use these couplers for different frequency requirements?
- This series offers a range of coupling values from 5dB to 30dB, allowing engineers to precisely balance signal levels across different branches of a DAS deployment while maintaining low insertion loss throughout the chain.
