Abstract:
1. A resonator device having a stacked arrangement of laminated layers including a plurality of dielectric layers formed of dielectric material, and at least one resonator comprising a short-circuit electrode, a first capacitor electrode and a second capacitor electrode, each electrode comprising at least a portion of a layer of electrically conductive material provided on a surface of one of the dielectric layers, wherein for said at least one resonator, the second capacitor electrode is disposed spaced from the short-circuit electrode and the first capacitor electrode, such that, in the stacking direction, the second capacitor electrode is separated from the short-circuit electrode by at least one of the dielectric layers and the second capacitor electrode is separated from the first capacitor electrode by at least one of the dielectric layers, the short-circuit electrode and the second capacitor electrode are electrically interconnected by a first electrical connection comprising at least one via hole in the form of a continuous through hole penetrating one or more of the dielectric layers and at least partially filled with conductive material so as to provide an electrical connection between both ends of the through hole, wherein said at least one via hole extends from and is electrically directly connected to at least one of the short-circuit electrode and the second capacitor electrode, and the short-circuit electrode layer and the first capacitor electrode layer are electrically inter connected by a second electrical connection distinct from the first electrical connection, such that the first and second electrical connections and the dielectric material between the first and second electrical connections form a transmission line that has an overall transmission line path length of from λ/200 to λ/5, that extends between the short-circuit electrode and the second capacitor electrode, and that is short-circuited at one end by the short-circuit electrode, wherein, for said at least one resonator, the first electrical connection comprises a first via hole section including one or more first via holes, and a second via hole section including one or more second via holes, said first and second via hole sections not overlapping along the electrical path of the first electrical connection, wherein the first via hole section is disposed, along the electrical path of the first electrical connection, near the short-circuit electrode and the second via hole section is disposed, along the electrical path of the first electrical connection, near the second capacitor electrode, the via holes of the first and second via hole sections each terminate at and are electrically interconnected by a common interconnection layer provided as at least a portion of a layer of electrically conductive material on a surface of one of the dielectric layers, the first via hole section has less or more via holes than the second via hole section, and wherein the one or more via holes of the first via hole section all penetrate a same set of one or more of the dielectric layers, and the one or more via holes of the second via hole section all penetrate a same set of one or more of the dielectric layers.
