  • Stacked dielectric filter
    Patent number: 6828881
    Abstract: A stacked dielectric filter includes a filter section which has first and second input side resonant electrodes and first and second output side resonant electrodes of two ¼ wavelength resonators, a converting section which has a plurality of strip lines, and a connecting section which connects the filter section and the converting section, wherein the filter section, the converting section, and the connecting section are formed in a dielectric substrate. The filter section is formed at an upper portion in the stacking direction of dielectric layers. The converting section is formed at a lower portion in the stacking direction. The connecting section is formed between the filter section and the converting section.
    Type: Grant
