Abstract:
Disclosed in the present invention is a radio frequency front-end module, comprising at least one driving amplifier and at least one power amplifier. The output end of the driving amplifier is connected to the input end of the power amplifier. The radio frequency front-end module is powered by a power supply when working. When a preset power switching condition is met, the at least one driving amplifier and/or the power amplifier is powered by the power supply and a battery supply. The radio frequency front-end module provided by the present invention can eliminate the limitation of insufficient working current of a power management chip on the overall maximum output power in a low-voltage and high-power working state, and meets the application requirements of the electronic device on an APT mode.
