| Abstract | A front-end module that uses a carrier aggregation scheme in which Band, which is selected from a low-frequency band group, and Band, which is selected from a high-frequency band group, are used simultaneously for communication includes a plurality of signal paths that connect a power amplifier module to an antenna element, and an antenna switch module that switches connection between the antenna element and the plurality of signal paths. Harmonics of Band have frequencies that are included in Band. The front-end module further includes a switch element disposed in a TDD transmission path. |
