Frequently Asked Questions
- Q1: How does the 698-3800MHz frequency range benefit 5G deployment?
- A: This ultra-wideband coverage includes the 3.5GHz (n78) band, which is essential for global 5G NR networks. It allows a single system to handle everything from 700MHz (low-band 4G/5G) to high-speed 5G mid-band signals.
- Q2: What is the significance of -150dBc PIM in DAS systems?
- A: A low PIM (≤-150dBc) rating prevents the component from becoming a source of interference. This ensures cleaner signals, reduces dropped calls, and maintains higher data rates in multi-operator IBS environments.
- Q3: Can this coupler be installed in outdoor locations?
- A: Yes, it is rated at IP65, meaning it is dust-tight and protected against water ingress. Along with a wide temperature range, it is robust enough for both indoor venues and outdoor DAS deployments.
- Q4: How does high isolation (up to 45dB) improve system performance?
- A: High isolation ensures that signals from the main transmission line do not leak back into other paths, maintaining signal purity and protecting sensitive BTS equipment from unwanted reflections.
- Q5: Is this series compatible with high-power base stations?
- A: Definitely. With an average power rating of 200W, these couplers can safely handle the output from most standard BTS and high-power remote radio units (RRU) without failure.
