Abstract:
A multiplexer is electrically connectable to an antenna terminal. A first power amplifier is electrically connectable to the multiplexer. A second power amplifier is electrically connectable to the multiplexer. A switch circuit switches between a first route passing through the multiplexer and a second route not passing through the multiplexer. In a high-frequency front end circuit, the first route is formed in a case of a carrier aggregation mode in which the first power amplifier and the second power amplifier are simultaneously used, and the second route is formed in a case of a single mode in which one of the first power amplifier and the second power amplifier is used.
