Abstract
An even-mode resonator filter is disclosed. The even-mode resonator filter is provided with high stability, and comprises: a first even-mode resonance module, a second even-mode resonance module, a first filter unit and a second filter unit. In the present invention, the first even-mode resonance module comprises a first resonance unit and a second resonance unit, and the second even-mode resonance module comprises a third resonance unit and a fourth resonance unit. By letting the second resonance unit be coupled to the first resonance unit as well as making the third resonance unit be coupled to the fourth resonance unit, the even-mode resonator filter of the present invention has the advantage of eliminating unexpected resonance.
