Patent attributes
A mobile terminal according to the present invention includes a main transmitter to amplify and transmit a first signal of a first frequency band through a first path and a second path, and an auxiliary transmitter to amplify and transmit a second signal of a second frequency band through a third path. The mobile terminal further includes a controller to control the amplified first signal and the amplified second signal to be combined with each other when the distortion signal is to occur in frequency bands adjacent to the first frequency band due to the amplified first signal, thereby providing a radio frequency (RF) front end and a mobile terminal with improved non-linearity.
