Patent attributes
Disclosed in the present invention are a radio frequency front-end transmission module, a chip, and a communications terminal. In the radio frequency front-end transmission method, an output matching circuit of at least one transmission channel is connected to a switch unit, and is connected to a radio frequency transmission path by using the switch unit; an output matching circuit of another at least one transmission channel is directly connected to the radio frequency transmission path. By means of the present invention, a matched transmission channel can be selected according to different frequency bands in different modes, and a control unit controls on and off of a corresponding amplification unit and the switch unit, to implement output of radio frequency signals of different frequency bands in different modes.
