| 摘要 | A high-frequency module includes a switch IC and a matching circuit. The high-frequency module includes a multilayer body. The switch IC and an inductor of the matching circuit are mounted on a top surface of the multilayer body. A top-surface land electrode on which a common terminal of the switch IC is mounted is connected to one end of a wiring conductor through a via-conductor. The other end of the wiring conductor is connected to a top-surface land electrode on which a terminal electrode at one end of the inductor is mounted, through a via-conductor. An end portion of the inductor on the side connected to the common terminal of the switch IC is disposed near the common terminal. Thus, the length of the wiring conductor is shortened and a parasitic capacitance is decreased. | ||

| 主权项 | 1. A high-frequency module comprising: an antenna connection terminal which is connected to an antenna; a plurality of input/output terminals to which communication signals are input or from which communication signals are output, respectively; a switch IC that includes a plurality of switch terminals which are individually connected to the plurality of input/output terminals, and a common terminal which is connected to the antenna connection terminal, and that connects the common terminal to each of the plurality of switch terminals in a switching manner; a matching circuit which is connected between the common terminal of the switch IC and the antenna connection terminal; and a multilayer body including a plurality of electrically insulating layers which are stacked on top of one another; wherein the switch IC is mounted on one principal surface of the multilayer body; the matching circuit includes a first inductor which is connected in series between the common terminal of the switch IC and the antenna connection terminal; and a first wiring line, which connects one end of the first inductor and the common terminal, is shorter than a second wiring line, which connects the other end of the first inductor and the antenna connection terminal. | ||
