Description
5G Interference Filter for C-Band VSAT - 3.7-4.2GHz Bandpass, Protects Satellite LNB
The C BAND 5G Filter provides essential protection for satellite communication systems against interference from nearby 5G signals. This anti-5G rejection filter is specifically designed to safeguard your VSAT equipment from signal saturation and loss.
Installation & Function
Satellite Dish → [C-Band 5G Filter] → LNB → Receiver
Installed between the satellite dish and LNB in the coaxial cable path, this filter rejects or heavily attenuates the 5G band while allowing the full 3.7-4.2 GHz satellite band to pass through unimpeded. This prevents strong nearby 5G signals from saturating the Low-Noise Block Downconverter (LNB) and causing signal degradation.
Key Features
  • LNB Frequency Range: 3.7~4.2 GHz (Customizable design available for different frequency requirements)
  • 100 MHz Guard Band for enhanced signal isolation
  • Advanced 5G rejection technology

How This Bandpass Filter Differs from Notch Filters



Feature Bandpass Filter Notch/Reject Filter
Primary Function Allows ONLY 3.7-4.2GHz through, blocks everything else Allows everything EXCEPT 5G band
Rejection Approach Rejects ALL frequencies outside passband Targets specific 5G frequencies only
Protection Level Higher - blocks multiple interference sources Lower - only blocks 5G interference
Insertion Loss Slightly higher (0.3-0.8 dB) Typically lower (0.2-0.5 dB)
Cost Higher Lower

The 3.7-4.2 GHz bandpass filter represents the premium solution for protecting VSAT systems from 5G interference. While more expensive than simple notch filters, it provides:

  1. Comprehensive protection against multiple interference sources

  2. Preservation of full C-Band spectrum access

  3. Professional-grade performance for critical communications

  4. Future-proofing against evolving RF environment

For enterprise, maritime, aeronautical, and broadcast VSAT applications where reliability is paramount, this bandpass filter solution is often the recommended choice despite its higher cost, as it addresses both current 5G interference and potential future interference scenarios.
