    Abstract: A front-end module includes a switch, a first filter including an input end connected to a first selection terminal, a second filter including input end connected to a second selection terminal, and an impedance matching circuit connected to a selection terminal, a pass band impedance when viewing the first filter side from a common terminal in a state in which the common terminal and only the first selection terminal are connected is different from a pass band impedance when viewing the second filter side from the common terminal in a state that the common terminal and only the second selection terminal are connected. When the common terminal and the first selection terminal are connected, the common terminal and the selection terminal are connected, and when the common terminal and the second selection terminal are connected, the common terminal and the selection terminal are not connected.

    Abstract: A radio-frequency module including a module substrate, a plurality of electronic components, a plurality of external connection terminals, a resin member, and a plurality of electrodes. The module substrate has first and second major surfaces that are opposite to each other. The plurality of electronic components are disposed at the major surface and at the major surface. The external connection terminals are disposed at the major surface and include a first external connection terminal. The resin member is disposed at the major surface. The plurality of electrodes are disposed at the major surface and coupled to the plurality of external connection terminals. The plurality of electronic components include a passive component disposed at the major surface. At least a portion of the first external connection terminal overlaps at least a portion of the passive component in plan view of the module substrate.

    Abstract: A high-frequency module includes a module substrate having major surfaces, and a module substrate having major surfaces. The major surface are disposed facing the major surface. A first electronic component includes a filter coupled to a power amplifier and a low-noise amplifier. A second electronic component includes a filter coupled to a low-noise amplifier. A third electronic component includes a switch coupled between filters and an antenna connection terminal. The first electronic component is disposed between the major surfaces, on the major surface, or on the major surface. The second electronic component is disposed between the major surfaces, on the major surface, or on the major surface where the first electronic component is not disposed. The third electronic component is disposed between the major surfaces, on the major surface, or on the major surface wherein neither of the first nor second electronic component is disposed.
