Tunable Band Reject Filters

Overview

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, K&L Microwave 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.
