Abstract
A filter module includes an inductor, a filter including first wiring, and second wiring between the inductor and the first wiring and being a direct-current floating potential. The inductor and the first wiring are magnetically coupled, the inductor and the second wiring are magnetically coupled, and the first wiring and the second wiring are capacitively coupled.
Claims14
A filter module comprising:
- an inductor;
- a filter including first wiring;
- and
- second wiring between the inductor and the first wiring;
- wherein
- the second wiring is a direct-current floating potential;
- the inductor and the first wiring are magnetically coupled, and the inductor and the second wiring are magnetically coupled;
- and
- the first wiring and the second wiring are capacitively coupled such that a high-frequency component generated from the magnetic coupling of the inductor and the first wiring and a high-frequency component generated from the magnetic coupling of the inductor and the second wiring have opposite phases.
