Product 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

Technical Specifications

Parameter	Specification
Input Frequency (RF)	3.7 ~ 4.2 / 3.8 ~ 4.2 / 3.9 ~ 4.2 / 4.0 ~ 4.2 GHz
Insertion Loss	0.45 dB (Max.)
Out-of-band Rejection (Guard band=100MHz)	60 dBc (Min.)
VSWR	2.2:1
Operating Temperature	-40 ~ +60℃
Output Connector	WR229G/F

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:

Comprehensive protection against multiple interference sources
Preservation of full C-Band spectrum access
Professional-grade performance for critical communications
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.
