Ceramic waveguide filter

Abstract

A ceramic waveguide filter is disclosed. According to at least one embodiment of the present disclosure, a ceramic waveguide filter forming a plurality of resonant blocks including a ceramic dielectric is provided, including an input end and an output end implemented as grooves having a predetermined depth on an outer surface of the ceramic waveguide filter, a plurality of resonators implemented as grooves having a predetermined depth on an outer surface of each of the plurality of resonant blocks, and at least one or more ultra-short delay adjusters adjacent to at least one of the input end and the output end, and implemented as one or more grooves having a predetermined depth on the outer surface of the ceramic waveguide filter.
