In today's rapidly evolving 5G technology landscape, the issue of frequency band interference has become increasingly prominent, especially for C-band satellite operations. Addressing the challenge of interference from 5G base stations has become a pressing matter. To this end, PBI has introduced the new C-Band band-pass anti-5G interference filter – WFP-3742, which, with its exceptional technical specifications and performance, provides robust protection for C-band satellite operations.

I. Rigorous Testing, Quality Assurance

The WFP-3742BPF anti-5G interference filter has undergone stringent performance and environmental testing, as well as practical field tests that include 5G signals. Test results indicate that the filter can reliably and effectively shield existing C-band satellite operations from interference carriers in adjacent frequency bands. Even with widespread deployment of 5G services, it ensures the normal operation of user services.

II. Highlights of Technical Specifications

Interface Standard: Uses a BJ40 flange interface, allowing for easy installation without a specific orientation.
Passband Frequency Range: Covers 3.7GHz to 4.2GHz, perfectly suited for C-band satellite operation requirements.
Input/Output Impedance: 50Ω, ensuring stable signal transmission.
VSWR (Voltage Standing Wave Ratio): Within the passband frequency range, VSWR ≤ 1.4 (≤ 1.3 typical), effectively reducing signal reflection and enhancing transmission efficiency.
Operating Temperature: -40℃ to 60℃, capable of adapting to various harsh environments and ensuring long-term stable operation of the filter.
In-band Insertion Loss: At room temperature, insertion loss ≤ 0.35dB (≤ 0.55dB typical), guaranteeing high-quality signal transmission.
Interference Signal Suppression Capability:
- Suppresses 5G signals from 3.4GHz to 3.5GHz with a suppression level ≥ 55dB (≥ 60dB typical).
- Suppresses 5G signals from 3.5GHz to 3.6GHz with a suppression level ≥ 55dB (≥ 60dB typical).
- Suppresses 5G signals from 4.8GHz to 4.9GHz with a suppression level ≥ 55dB (≥ 70dB typical). This powerful suppression capability ensures that C-band satellite operations are immune to 5G signal interference.

III. Easy Installation, Simple Maintenance

When installing the WFP-3742 anti-5G interference filter, the protective film on the interface does not need to be removed. This film does not affect signal passage and also provides dust and foreign object exclusion for the cavity. Additionally, during installation, bolts should be tightened as much as possible to ensure a tight connection for optimal filter performance.

IV. Legal Compliance, Wide Application

The WFP-3742BPF filter has obtained the Network Access License from the Radio and Television Administration, allowing for legal and widespread application in broadcast and television projects. This not only provides users with legal protection but also further broadens the filter's application scenarios.

In summary, the C-Band anti-5G filter WFP-3742, with its exceptional technical specifications and performance, has become the ideal choice for protecting C-band satellite operations from 5G interference. Whether considering test validation, technical specifications, installation convenience, or compliance, WFP-3742 demonstrates unparalleled advantages. Choosing WFP-3742 is choosing a stable, reliable, and efficient protection solution for C-band satellite operations.
