Abstract

A multi-mode power amplifying circuit, and a multi-mode wireless transmission module and method thereof are provided. The multi-mode wireless transmission module includes the multi-mode power amplifying circuit and an antenna. In the multi-mode power amplifying circuit and the antenna, a first power amplifier is electrically connected between a signal input end and a first impedance matching circuit, and an output end of the first impedance matching circuit is electrically connected to the antenna. A second power amplifier is electrically connected to the signal input end, and a second impedance matching circuit is electrically connected between the second power amplifier and the first impedance matching circuit. A switching circuit is electrically connected to an input end of the second impedance matching circuit. The switching circuit switches on-off corresponding to an operation of the first power amplifier and an operation of the second power amplifier.
