Original Abstract Submitted
A filter device includes a stack including a plurality of dielectric layers stacked together, and a resonator configured using a conductor integrated into the stack. Each of the plurality of dielectric layers is formed of a dielectric material, and has a resonance frequency that changes depending on a temperature. In the dielectric material, the resonance frequency changes linearly with respect to a change in the temperature when the temperature is within a first temperature range, and the resonance frequency changes nonlinearly with respect to the change in the temperature when the temperature is within a second temperature range.
