BSC, K&L Microwave®, and Pole/Zero® fixed and tunable band reject filters.
With Band Reject Filters, also known as a Band Stop Filters, frequencies are attenuated in the stop band and passed outside these parameters. Notch Filters also fall under the category of Band Stop Filters, as they reject frequencies, but in a highly selective, high-Q form.
All Band Reject Filters or Band Stop Filters made by Microwave Products Group, including Notch Filters, are available as a wideband or narrowband reject filter and can be customized to user specifications. For example, Notch Filters are most commonly applied to applications where it is necessary to attenuate a single frequency. However, utilizing our cross-industry experience, MPG can customize Notch Filters to reject two very narrow band signals while monitoring broadband for out-of-band spurious or harmonic radiations.
MPG’s experienced engineers work individually with client engineers to determine the best filter types for each application, covering a wide range of frequencies and bandwidths.
Band Reject Filter frequency: VHF and UHF from 800 KHz to 18 GHz (L band, S band, C band, X band, Ku band). Band Reject Filter (Band Stop Filter) features: Band Reject Filters are available as fixed and tunable, narrowband filters or wideband filters, supporting bandwidths from 1% to 200%, in configurations and topologies.
Because MPG Band Reject Filters are custom-fit to end-user specifications, they are applicable to a wide range of use cases, including those in the following markets: defense, EW, RADAR, communications, SATCOM, telecom, SIGINT, aerospace, space, automated test equipment, navigation/GPS and data links.
