Abstract:
Disclosed are embodiments of ceramic radiofrequency filters advantageous as RF components. The ceramic filters can include a ceramic stepped impedance resonator, wherein the inner diameter of the ceramic stepped impedance resonator can vary from one end to another end. The inner diameter can be, for example, tapered, sectioned, or stair-stepped in order to provide different impedances in the ceramic resonator.
