US 2025/0105482 A1 · E-PLANE CERAMIC WAVEGUIDE FILTER

Abstract

E-plane waveguide filters, and methods for manufacturing the same, are described herein. In one aspect, a filter may include a first dielectric block (e.g., including a first coupling structure) and a second dielectric block (e.g., including a second coupling structure). A septum may be formed by a union of the first coupling structure and the second coupling structure, e.g., eliminating the need for a separate septum. Moreover, one or more of resonators, a metalized septum for inter-resonator couplings, and/or various input and output couplings loops or probes for input loading into the filter may be pressed, machined, lased, or screen printed onto\into the blocks. By reducing the part count of the E-plane filter and/or decreasing its complexity, the structure of the E-plane filter may be manufactured for efficiently and its cost may be decreased.
