垂直共振器を有する積層RFデバイス
Document Type and Number:
Japanese Patent JP2011507312
Kind Code:
A
Abstract:
The present invention relates to a resonator device having a stacked arrangement of laminated layers including a plurality of dielectric layers (3a, 3b, 3c), and at least one resonator (2) comprising a short-circuit electrode (4, 4'), a first capacitor electrode (5') and a second capacitor electrode (7). Each electrode (4, 4', 5', 7) comprises at least a portion (4', 5', 7) of a layer (4, 5, 7) of electrically conductive material provided on a surface of one of the dielectric layers (3a, 3b, 3c). The second capacitor electrode (7) is disposed spaced, in the stacking direction, from the short-circuit electrode (4, 4') and the first capacitor electrode (5'). The short-circuit electrode (4, 4') and the second capacitor electrode (7) are electrically interconnected by means of a first electrical connection comprising at least one via hole (8, 8a, 8b) penetrating one or more of the dielectric layers (3a, 3b, 3c). At least one of these via holes (8, 8a, 8b) extends from and is electrically directly connected to the short-circuit electrode (4, 4') and/or the second capacitor electrode (7). The short-circuit electrode layer (4) and the first capacitor electrode layer (5) are electrically interconnected by means of a second electrical connection distinct from the first electrical connection. The first and second electrical connections and the dielectric material (3) between them form a transmission line that has an overall transmission line path length of from »/200 to »/5, that extends between the short-circuit electrode (4, 4') and the second capacitor electrode (7), and that is short-circuited at one end by the short-circuit electrode (4, 4'). Further, the present invention relates to an RF device comprising and to a method of manufacturing such a resonator device.
