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.
A stacked dielectric filter comprising a filter section having a plurality of resonators for filtering an unbalanced signal, and at least one unbalanced-balanced converting section having strip lines, said filter section and said unbalanced-balanced converting section being in a dielectric substrate including a plurality of stacked dielectric layers, wherein said unbalanced-balanced converting section is connected via a connecting section to an input side and/or an output side of said filter section.
