Abstract
A multilayered filter device includes a first port, a second port, a first LC resonator electrically connected to the first port, a second LC resonator electrically connected to the second port, a third LC resonator provided between the first LC resonator and the second LC resonator in a circuit configuration, and a stack. The first LC resonator includes a first inductor. The second LC resonator includes a second inductor. The first inductor and the second inductor are configured to be magnetically coupled inside the stack.

A multilayered filter device comprising:
- a first port;
- a second port;
- a first LC resonator electrically connected to the first port;
- a second LC resonator electrically connected to the second port;
- a third LC resonator provided between the first LC resonator and the second LC resonator in a circuit configuration;
- and
- a stack that includes a plurality of dielectric layers stacked together, and that is configured to integrate the first port, the second port, the first LC resonator, the second LC resonator, and the third LC resonator, wherein
