Title:
CERAMIC WAVEGUIDE FILTER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/111397
Kind Code:
A1
Abstract:
The present invention provides a ceramic waveguide filter and a method for manufacturing same, the ceramic waveguide filter comprising: multiple resonant cavities defined by multiple through-partition walls in a single ceramic block, the through-partition walls being formed to divide the ceramic block into sections according to a predetermined pattern; multiple resonant grooves formed in the sections of the multiple resonant cavities, divided by the through-partition walls; a metal layer formed on the inner surface of each of the multiple through-partition walls; and input/output interfaces formed in two resonant cavities for input and output of signals among the multiple resonant cavities. By forming the resonant grooves in the sections of the resonant cavities, a small-sized ceramic waveguide filter with improved spurious characteristics can be manufactured.
