Abstract:
1. A high-frequency laminated component comprising: a pair of input/output terminals; and a ground impedance adjustment circuit defined by a series capacitor connected between the pair of input/output terminals, and a first parallel capacitor and a second parallel capacitor respectively connected between the opposite ends of the series capacitor and a ground; wherein the ground impedance adjustment circuit is defined by a laminate of a plurality of laminated insulating layers provided with predetermined electrode patterns; two inner-layer ground electrodes are respectively provided on different intermediate layers of the laminate; at least two via holes extend between and connect the two inner-layer ground electrodes directly to one another; a first electrode of the first parallel capacitor and a first electrode of the second parallel capacitor are disposed in a first layer that is arranged between the two inner-layer ground electrodes; a second electrode of the first parallel capacitor and a second electrode of the second parallel capacitor are disposed in a second layer that is arranged between the two inner-layer ground electrodes; a first electrode of the series capacitor is disposed in a third layer that is arranged between the first layer and the second layer; the first electrode of the series capacitor at least partially overlaps each of the first and second electrodes of the first parallel capacitor in a lamination direction; the first electrode of the series capacitor at least partially overlaps each of the first and second electrodes of the second parallel capacitor in the lamination direction; and the high-frequency laminated component further comprises:
