Title:
CERAMIC WAVEGUIDE FILTER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/111396
Kind Code:
A1
Abstract:
The present invention provides a ceramic waveguide filter and a method for producing same, the ceramic waveguide filter comprising: multiple resonant cavities defined by multiple penetrating partitions formed to divide a single ceramic block into sections according to a predetermined pattern in the ceramic block; a metal layer formed on the inner surface of each of the multiple penetrating partitions; and input/output interfaces for inputting and outputting signals, the input/output interfaces being formed at two resonant cavities among the multiple resonant cavities. Accordingly, the ceramic waveguide filter can be integrally produced with a single ceramic block so as to enable production thereof through a simplified production process and with a low cost, minimize processing errors, and be easily tunable even when a property change occurs during production. In addition, the present invention can easily generate a transmission zero.
