<p>In the present invention, the method used to attenuate leakage of a transmitted signal is changed in accordance with transmission power and reception performance. A mobile communication terminal is provided with a main antenna, a sub-antenna, a first main front end, a first sub-front end, a second main front end, a second sub-front end, a main diplexer, a sub- diplexer, and a switch. The switch is controlled on the basis of the transmission power of a first frequency band, the transmission power of a second frequency band, the reception performance of the first frequency band, and the reception performance of the second frequency band, and it is determined whether the diplexer or a different antenna is to be used in order to attenuate leakage of the transmitted signal to other frequency bands.</p> |
