Abstract: A multiplexer includes a first filter disposed on a first signal path, a second filter disposed on a second signal path different from the first signal path, the second filter having a passband different from that of the first filter, a common connection point at which the first signal path and the second signal path are connected to each other, and an inductor disposed in series on a path connecting the common connection point and the first filter, the path being a portion of the first signal path. On the first signal path, a distance connecting the common connection point and the inductor is shorter than a distance connecting the inductor and the first filter.

Abstract: A semiconductor device includes a base, a first switching unit disposed on the base, the first switching unit having a substantially rectangular shape and including plural first switches, and an amplifier unit disposed on the base, the amplifier unit including plural amplifier circuits to which a radio-frequency signal is inputted after passing through the first switching unit. In plan view of the base, the first switching unit has four edges including a first edge, a second edge orthogonal to the first edge, and a third edge parallel to the first edge and orthogonal to the second edge, the amplifier unit includes a first region extending along the first edge, a second region extending along the second region, and a third region extending along the third edge, and at least one of the plural amplifier circuits is disposed in each of the first region, the second region, and the third region.
