Stacked LC filter with a pole-adjusting electrode facing resonator coupling patterns
A stacked LC filter includes a layered body defined by a plurality of insulating layers, a plurality of inductor patterns, and a plurality of capacitor patterns in a stacked arrangement At least three LC resonators are disposed in the layered body including a plurality of inductors, which are defined by the inductor patterns, and a plurality of capacitors, which are defined by the capacitor patterns disposed so as to face the inductor patterns. At least two coupling capacitor patterns are stacked in the layered body and are arranged to couple the LC resonators. A pole adjusting pattern is stacked in the layered body and faces the at least two coupling capacitor patterns.
