UHF Notch Filter

The model 5NSP-445.25/X20-O/O is a notch filter optimized for steep skirts, and for low-loss. By exploiting mixed technologies, such as TEM resonators, suspended-substrate strip-lines and lumped components, the filter exhibits the best trade-offs of performance-to-volume ratio. There are several applications for this filter, ranging from rejecting signals at around 445 MHz from a nearby Tx antenna, to eliminating an unwanted harmonic from a transmitter, while the rest of the spectrum remains unaffected. In either case, the band-reject filter serves as a “quick fix” to everyday field solutions. This feature is enabled, due to the broadband matching of the device, from DC to 1000 MHz, by simply connecting the filter in line with the antenna.
