Ceramic waveguide filter including a plurality of resonators and ultra-short delay adjusters each formed by respective groove-shaped portions

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 each defined by a groove-shaped portion having a predetermined depth on an outer surface of the ceramic waveguide filter, a plurality of resonators each defined by a groove-shaped portion having a predetermined depth on an outer surface of each of the plurality of resonant blocks, and at least one ultra-short delay adjusters adjacent to at least one of the input end and the output end, the ultra-short delay adjuster being defined by a groove-shaped portion having a predetermined depth on the outer surface of the ceramic waveguide filter.

Dependencies are inferred from the claim text.
