摘要:
Disclosed in the present invention are a multimode and multi-frequency radio frequency front end module, a chip, and a communication terminal. The radio frequency front end module comprises an input matching unit, an amplification unit, a first output matching module, a first switch module, a second matching module, and a control unit. The control unit is connected to the first switch module and is used for controlling a switch state of the first switch module, so as to input a radio frequency signal to one or more radio frequency transmission paths. According to the present invention, radio frequency transmission paths matching the radio frequency front end module can be selected according to different frequency bands under different modes and the control unit controls corresponding switches to be in switch-off and switch-on states, thereby implementing output of radio frequency signals at the different frequency bands under the different modes
