Abstract
A front-end circuit includes a switching circuit and a low-pass filter. The switching circuit includes common terminals and to-be-selected terminals. The common terminals are connected to each other, and a connection point at which the common terminals are connected to each other is connected to an antenna. The common terminal is directly connected to the connection point. The common terminal is connected to the connection point with the low-pass filter interposed there between.
