An iris waveguide bandpass filter is a filter whose resonators (cavities) are delimited by “iris” of different openings. The iris can be capacitive or inductive depending on their orientation. Iris-coupled filters are of great interest for the production of filters with wider passbands, low insertion losses, with a high quality coefficient and high rejection.

The following calculator is used to size a filter (size and necessary order) to meet your specifications.
