Abstract: Multiple-pole resonator filter. In some embodiments, a filter for radio-frequency application can include a first coaxial resonator in a first orientation and having an input on a first side of the filter defined by N coaxial resonators, and an N-th coaxial resonator in the first orientation and having an output on the first side of the filter. The filter can further include a second coaxial resonator in a second orientation opposite the first orientation to form a first interdigitation with the first coaxial resonator, and an (N?1)th coaxial resonator in the second orientation to form a second interdigitation with the N-th coaxial resonator. The filter can further include one or more coaxial resonators coupled between the second and (N?1)th coaxial resonators, such that the N coaxial resonators have slot coupling between adjacent ones of the N coaxial resonators.

Abstract: Devices and methods related to multiple-pole ceramic resonator filters. In some embodiments, a radio-frequency (RF) filter can include a first coaxial resonator in a first orientation and having an input tab on a first side of the filter, and an N-th coaxial resonator in the first orientation and having an output tab on the first side of the filter. The RF filter can further include second and (N?1)th coaxial resonators, each in a second orientation opposite the first orientation to form first and second interdigitations with the first and N-th resonators, respectively. The RF filter can further include at least two coaxial resonators in the first orientation and coupled between the second and (N?1)th resonators. The N resonators can be slot coupled between the first and N-th resonators. The first and second interdigitations can be configured to provide enhancement of the slot coupling between the first and N-th resonators.
