摘要： A filter includes: a converter circuit, provided with a single-type common terminal and two balanced terminals, for performing conversion between a balanced line and an unbalanced line; two filter units coupled to each of the balanced terminals of the converter circuit and allowing passage of a signal in a pass band; and a bridging capacitor arranged to extend across the converter circuit and one of the filter units in a bridging manner, wherein the inductance of an opposite-side line of one of the filter units relative to the converter circuit is electromagnetically coupled to the inductance of a line coupling the other filter unit and the converter circuit.
