RESONACNE DEVICE AND FILTER INCLUDING THE SAME

摘要

A resonance device having ports for input or output according to an embodiment of the present invention comprises: resonators which are separated each other; and a notch resonator formed on one side of the resonators. The notch resonator comprises: a stack part in which a plurality of conductor layers are stacked; a first transmission layer connected to one of the conductor layers; and a bridge connected to the first transmission layer and one of the resonators. One of the ports is connected to the bridge. The resonance device and a filter including the same have superior narrowband features and superior blocking features.
