C-Band 5G Filter
With the dense deployment of 5G communication networks near the C-band spectrum, strong 5G signals in the 3.3-3.6GHz band pose a serious interference threat to C-band satellite reception systems (3.7-4.2GHz). These 5G signals can cause the LNB (Low-Noise Block Downconverter) to saturate, resulting in signal loss, quality degradation, and even communication interruption.
The C-Band 5G Filter is specifically designed to address this challenge. Installed on the coaxial cable between the satellite dish and LNB, it effectively rejects 5G band signals while allowing the full 3.7-4.2GHz satellite band to pass through with minimal loss – ensuring your VSAT system remains stable and reliable in the 5G era.

Q: Why do I need a C-Band 5G Filter?
A: 5G networks deploy in the 3.3-3.6GHz band, adjacent to the C-band satellite reception band (3.7-4.2GHz). Strong 5G signals can cause LNB saturation, leading to signal quality degradation and even communication interruption. This filter removes 5G interference before it enters the LNB, effectively protecting your satellite system.
Q: What does 0.45dB insertion loss mean?
A: 0.45dB is an extremely low loss level. For a 3.7-4.2GHz signal, 0.45dB insertion loss represents only about 10% power loss – minimal impact on actual signal quality. Picture quality remains unaffected.
Q: How strong is 60dBc rejection capability?
A: 60dBc means 5G band signals are attenuated to one millionth (1/1,000,000) of their original power. This is very strong rejection capability, effectively protecting the LNB from saturation by strong 5G signals.
Q: What frequency configurations does this filter support?
A: Standard versions support multiple passband configurations including 3.7-4.2 / 3.8-4.2 / 3.9-4.2 / 4.0-4.2 GHz. Custom designs for other frequencies are also available upon request.
Q: What is the operating temperature range?
A: -40℃ to +60℃ – suitable for most climate conditions, from cold northern winters to hot southern summers.
Q: What type of interface does it have?
A: WR229G/F waveguide interface – the standard C-band interface, compatible with mainstream C-band LNBs and antenna systems.
