<p>Disclosed are a power amplification module, a radio frequency front-end module, a multi-mode radio frequency transceiver, a multi-mode terminal and a method for a multi-mode terminal to send signals. The power amplification module includes a control module and a lower frequency amplifier and a high frequency amplifier connected to the control module. The control module is used for sending an operating mode indication signal to the lower frequency amplifier or the high frequency amplifier according to a control signal from a baseband chip. The lower frequency amplifier is used for receiving a low frequency transmission signal and the operating mode indication signal sent by the control module and amplifying the low frequency transmission signal under the operating module indicated by the operating mode indication signal and outputting same. The high frequency amplifier is used for receiving a high frequency transmission signal and the operating mode indication signal sent by the control module and amplifying the high frequency transmission signal under the operating module indicated by the operating mode indication signal and outputting same. A multi-mode terminal including the above-mentioned power amplification module can effectively reduce the occupied printed circuit board (PCB) area.</p> |
