Einführung in das Hauptprodukt
This 300W directional coupler is an essential component for critical communication systems and high-capacity In-Building Solutions (IBS). It utilizes a high-isolation air-dielectric architecture that ensures thermal stability and electrical reliability across the entire VHF/UHF spectrum. By providing an accurate sample of the forward signal, it enables network operators to monitor system health and RSSI without interrupting service in life-safety environments.
- Breiter Frequenzbereich: 150 – 1000 MHz (Covers VHF, UHF, FirstNet, and Sub-1GHz LTE).
- Hohe Leistungskapazität: 300W (Ideal for high-power BTS transmitters and trunking systems).
- Geringe Einfügungsdämpfung: ≤ 0.3-0.4 dB (Negligible impact on the primary transmission link).
- Hervorragende PIM-Leistung: Rated at ≤ -150 dBc (Available in Low PIM 4.3-10 configurations).
- Hohe Richtwirkung: Ensures accurate forward power sampling independent of antenna reflections.

Häufig gestellte Fragen
- How does the 300W power rating benefit Public Safety trunking systems?
- High-power trunking systems often aggregate multiple carriers, creating high peak power levels. The 300W rating provides a massive safety margin, ensuring the coupler can handle high-output BTS signals without saturation or thermal failure, which is critical for 24/7 mission-critical uptime.
- Can this coupler be used for both VHF and UHF signal monitoring simultaneously?
- Yes. The 150-1000MHz bandwidth is continuous. This allows a single unit to sample signals across the entire VHF (150MHz) and UHF (450MHz+) spectrum, as well as 700/800MHz Public Safety LTE, reducing the need for multiple band-specific components.
- What is the advantage of choosing the 4.3-10 connector version for Sub-1GHz LTE?
- In cellular deployments (like Band 14/28), Passive Intermodulation (PIM) can degrade receiver sensitivity. While N-type is standard for VHF/UHF, the 4.3-10 connector is designed specifically to maintain a stable, Low PIM (≤-150dBc) connection, ensuring that high-power forward signals do not create interference that slows down data throughput.
