Cavity Bandpass Filter, 4,760 – 4,780 MHz, TNC(m) and TNC(f) RF Connectors
Southwest Antennas Part # 1080-189 is a small cavity bandpass filter designed for operation in federal C-Band radio network applications, with a center frequency of 4,770 MHz and a 20 MHz wide pass band of 4,760 – 4,780 MHz.
The narrow 20 MHz pass band is designed to offer the best performance and out-of-band rejection possible for users with narrow channel assignments, while still maintaining a physically compact product that can be easily integrated into deployed radio systems.
This cavity bandpass filter offers excellent -60 dB out-of-band rejection and is designed to be installed in-line between the radio and antenna, or integrated within other communication equipment when additional RF filtering is required to improve network performance. This bandpass filter is ideal for tactical radio systems, fixed site infrastructure, base station systems, network nodes, or other communication network infrastructure that operates in congested, high-interference RF environments.
Southwest Antennas bandpass filters can be utilized to help eliminate interference by rejecting out-of-band noise from other co-located radios operating outside of the filter's operational bandpass range, providing increased performance for radio systems and attached antennas.
Note: Other federal C-Band cavity filters with a 20 MHz pass band are available from 4,400 MHz to 4,940 MHz in the same form factor. Contact Southwest Antennas or visit our website for details.
