Anti-5G Ku-Band Filter
High-Performance Anti-5G Interference · Precise Frequency Control · Safeguarding Pure Ku-Band Signals
With the continuous expansion of 5G networks in the sub-6GHz spectrum, while primary interference concerns remain in the C-band, Ku-band satellite communication systems also face increasingly complex electromagnetic environment challenges. High-frequency electronic equipment, adjacent band signals, and increasingly dense wireless communication infrastructure can all cause interference to sensitive Ku-band receiving systems.
The Ku-Band 5G Filter is a high-performance bandpass filter specifically designed for Ku-band satellite communication systems. Installed between the satellite dish and LNB, it allows the 10.7-12.75GHz satellite band to pass through with ultra-low insertion loss, while providing up to 70dBc deep rejection of interference signals in the 13.75-14.5GHz transmit band – ensuring your Ku-band receiving system remains stable and reliable in complex electromagnetic environments.

Q: Why does Ku-band still need a 5G filter?
A: While primary 5G interference concerns remain in the C-band, increasingly complex urban electromagnetic environments mean various wireless devices (including 5G base stations, microwave links, radar, etc.) can generate harmonics and out-of-band emissions that may interfere with Ku-band receiving systems. This filter provides professional out-of-band interference rejection, ensuring stable Ku-band system operation in complex electromagnetic environments.
Q: What does 0.20dB insertion loss mean?
A: 0.20dB is an industry-leading ultra-low loss level. For Ku-band signals, 0.20dB insertion loss represents only about 4.5% power loss – minimal impact on actual signal quality. Picture quality remains unaffected.
Q: How strong is 70dBc rejection capability?
A: 70dBc means interference band signals are attenuated to one ten-millionth (1/10,000,000) of their original power. This is very strong rejection capability, effectively filtering out-of-band interference signals.
Q: What frequency bands does this filter support?
A: Passband covers the 10.7-12.75GHz full Ku-band receive band, rejecting 13.75-14.5GHz transmit band interference. Compatible with all Ku-band satellite receiving systems.
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: WR75G/F waveguide interface – the standard Ku-band interface, compatible with mainstream Ku-band LNBs and antenna systems.
