Abstract: A multilayer bandpass filter includes a first capacitor electrode of a first stage LC parallel resonator, a second capacitor electrode of a second stage LC parallel resonator, and a third capacitor electrode of a third stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the first stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the second stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the third stage LC parallel resonator. The inductor electrodes of the three LC parallel resonators are arranged so loop planes thereof are disposed about a center axis extending in a stacking direction of dielectric layers. This permits setting of electromagnetic coupling between the LC parallel resonators of an input and an output stage, and allows a filter's attenuation characteristics to be freely set.

Abstract: In a high frequency filter, a multilayer structure includes a plurality of insulator layers, a first transmission line transmits an input signal, and a second transmission line is electromagnetic coupled with the first transmission line on the same insulator layer and transmits an output signal. A conductor layer defines capacitors with the first transmission line and the second transmission line with the insulator layer in between. A dielectric constant of the insulator layer that comes in contact with the first transmission line and the second transmission line is higher than a dielectric constant of an insulator layer other than the insulator layer.
