Abstract
A high-frequency filter () includes resonators (, and), an inductor (), and a switch (). The resonator () is connected between a first input/output terminal (P) and a second input/output terminal (P). One end of the inductor () is connected between the resonator () and the first input/output terminal (P). One end of the resonator () is connected to the other end of the inductor (). The switch () selects either a connection portion that connects the inductor () and the resonator () or the resonator () and connects either the connection portion or the resonator (), which has been selected, to a terminal of the resonator () on the side of the second input/output terminal (P). The switching between the connection modes of the switch () changes the circuit configuration of the high-frequency filter ().
