PBI WFP-3742

C-Band Filter / Anti-5G Interference Filter

Product Model:​ WFP-3742

Product Description

To address the challenge of severe interference from 5G base stations, PBI has released the new C-band bandpass anti-5G interference filter, model WFP-3742

The WFP-3742 BPF (Bandpass Filter) has undergone rigorous performance and environmental testing, as well as actual field tests involving 5G signals. Test results indicate that the WFP-3742 BPF can reliably and effectively protect existing C-band satellite services from interference caused by adjacent frequency carriers.

By utilizing the WFP-3742 BPF, users of C-band satellite services are expected to benefit from uninterrupted operations even amidst widespread 5G deployments.

The WFP-3742 BPF filter has obtained the network access license from the National Radio and Television Administration (NRTA), authorizing its legal and extensive application in radio and television projects.

Installation Guidelines

• The WFP-3742 Anti-5G Interference Filter features a standard CR299 interface; installation is non-directional (no front or back).
• Do not remove the protective film covering the interface during installation. This film does not affect signal transmission and serves to prevent dust and foreign objects from entering the cavity.
• Ensure bolts are tightened securely during installation to guarantee a tight and robust connection.
