MULTIBAND FILTER

摘要

According to one embodiment, a multiband filter includes a first resonator and a second resonator. The first resonator has a first capacitive component and a first inductive component. A signal of a first frequency is inputted to the first resonator. The second resonator has a second capacitive component and a second inductive component. A signal of a second frequency 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.
