Zusammenfassung:A coupled line filter includes: a first line resonator connected input port and a second line resonator connected with output port each having an electrical length of 270° at a predetermined center frequency, the first and second line resonators being disposed parallel to each other; and a third line resonator including one or more line resonators disposed between the first line resonator and the second line resonator, each line resonator having an electrical length of 90° at the center frequency and a first side aligned with first sides of the first line resonator and the second line resonator, wherein an order of the coupled line filter is determined by summing the number of the line resonators included in the third line resonator and the first and second line resonators.
