Document Type and Number:
WIPO Patent Application WO/2023/138615
Kind Code:
A1
Abstract:
Disclosed are a radio frequency front-end module having a current protection function, and an electronic device. The radio frequency front-end module comprises an input matching module, a power amplifier, an output matching module, a power supply module, and a protection unit. An input end of the input matching module is connected to an external radio frequency signal input end, an output end of the input matching module is connected to an input end of the power amplifier, an output end of the power amplifier is connected to an input end of the output matching module, and an output end of the output matching module is connected to a radio frequency signal output end; output ends of the power supply module and the protection unit are respectively connected to the power amplifier. The protection unit can achieve the effects of current protection, voltage protection and power protection for the power amplifier in the radio frequency front-end module, so that the reliability and safety for the radio frequency front-end module to operate in a severe environment are improved.
