Abstract:
A high-frequency front end module includes a primary antenna terminal and a secondary antenna terminal, a first multiplexer and a second multiplexer, a switch circuit, and a first amplifier and a second amplifier. The first multiplexer has a first transmission filter and a first reception filter. The second multiplexer has a second transmission filter and a second reception filter. The switch circuit exclusively switches connection between the primary antenna terminal and the first multiplexer and connection between the primary antenna terminal and the second multiplexer, and exclusively switches connection between the secondary antenna terminal and the first multiplexer and connection between the secondary antenna terminal and the second multiplexer.
