Frequently Asked Questions
- Q1: Why is the 4000MHz frequency support important?
- A: Most standard attenuators stop at 2700 or 3800MHz. Supporting 4000MHz (4.0GHz) ensures that this device is fully compatible with the extended 5G NR (New Radio) bands and high-frequency Wi-Fi applications, providing better future-proofing for your network.
- Q2: What is the benefit of -160dBc Low PIM in a small 2W attenuator?
- A: Even at low power (2W), passive components can generate intermodulation distortion that interferes with signal reception. A -160dBc PIM rating ensures that this attenuator maintains the ultra-clean signal environment required by modern high-speed data networks.
- Q3: When should I choose a 2W attenuator over a higher power model?
- A: A 2W attenuator is ideal for signal leveling in small cells, laboratory testing, or after a splitter/coupler where the signal power has already been significantly reduced. For direct connection to a base station output, we recommend our 50W or 100W models.
- Q4: How does the attenuation accuracy impact my system budget?
- A: Accuracy (from ±0.8 to ±1.5dB) defines the deviation from the nominal attenuation value. High accuracy ensures that the actual signal level at the receiver is exactly what you planned in your link budget, preventing dropped connections due to weak signals.
- Q5: What makes the 4.3-10 connector superior to the N-type?
- A: The 4.3-10 connector is specifically designed for low-PIM performance and has a smaller footprint. It provides a more reliable mechanical connection and better electrical performance, making it the preferred choice for modern 4G and 5G In-building Solutions (IBS).
