A noise suppression filter includes a resonator, a ground plane, and a set of differential transmission lines. The set of differential transmission lines includes a first meander line and a second meander line formed in a first circuit layer. The resonator is formed in a second circuit layer and includes a first long arm, a second long arm, and a short arm extended form a same point to form a T-shape. The ground plane is formed in a third circuit layer and is coupled to the first long arm and the second long arm through vias. The first meander line is detoured along the inner sides of the first long arm and the short arm, and the second meander line is detoured along the inner sides of the second long arm and the short arm.
