Abstract
A laminated filter comprising a laminated body created by laminating a plurality of dielectric sheets, a resonator electrode disposed on an inner part of the laminated body, and an input-output electrode disposed on the inner part of the laminated body at a position facing the resonator electrode through the dielectric sheet. A stub electrode is connected to the input-output electrode.
Claims4
A laminated filter comprising:
- a laminated body created by laminating a plurality of dielectric sheets together;
- plurality of resonator electrodes disposed on a first of said plurality of inner dielectric sheets, and including an input resonator electrode and an output resonator electrode;
- a first input-output electrode disposed on a second of said plurality of dielectric sheets;
- and
- a second input-output electrode disposed on said second of said dielectric sheets, said second of said sheets disposed parallel to said first of said dielectric sheets;
- wherein said first input-output electrode is disposed facing said input resonator electrode, said second input-output electrode is disposed facing said output resonator electrode, and at least one of said first and second input-output electrodes is coupled to a stub electrode disposed on said second of said dielectric sheets and having an open-circuit end, and
- said stub electrode is disposed at a position not overlapping said resonator electrodes.
