The present invention belongs to the technical field of radio frequency. Disclosed are a transmission power adjustment module, a radio-frequency front-end module, and a wireless transmission device. The transmission power adjustment module comprises a signal receiving end, a low-noise amplifier, a signal coupler, a signal output end, a coupling-signal amplifier, a rectifier module, a first transistor, a second transistor, a first switch, a capacitor, a second switch, a third transistor, a fourth transistor and an adjustable resistor module. The transmission power adjustment module in the present invention can not only adjust the transmission power of a power amplifier in a radio-frequency front-end module, such that the power amplifier does not perform transmission at the maximum power all the time, thereby reducing radiation, reducing power consumption and heat generation, and prolonging the service life, but can also make the implementation process simpler.
