Title:
マルチバンドフィルタ
Document Type and Number:
Japanese Patent JP6490928
Kind Code:
B2
Abstract:
According to one embodiment, a multiband filter includes a first resonator(220) and a second resonator(230). The first resonator has a first capacitive component(C l1 ) and a first inductive component(L l1 ). A signal of a first frequency(f l ) is inputted to the first resonator. The second resonator has a second capacitive component(C h1 ) and a second inductive component(L h1 ). A signal of a second frequency(f h ) is inputted to the second resonator. The second frequency is different from the first frequency. A distance between a first capacitive component of the first resonator and a second capacitive component of the second resonator and a distance between a first inductive component of the first resonator and a second inductive component of the second resonator is longer than a shortest distance out of a distance between the first resonator and the second resonator. The capacitive components occur at the capacitance. The inductive components occur at the inductance.
