Abstract

A front-end circuit includes a primary circuit and a diversity circuit, the primary circuit includes transmission pathsandfor transmitting a signal in a band A and in a band B, respectively. Transmission and reception of a signal in the band B are performed by a TDD system in the transmission path. The diversity circuit includes a switch, and reception pathsandthat receive a signal in the band A and in the band B, respectively. When reception signals in the band A and in the band B are simultaneously transmitted, and when a reception signal in the band A and a transmission signal in the band B are simultaneously transmitted, the switch causes the diversity antenna and each of the reception pathand the reception pathto be in a conductive state.
