The present invention discloses a batch detecting method and a device for a power amplifier. The present invention comprises a power shunt module, a high power attenuator module, a power detection module and a control circuit module. The power shunt module is used for shunting a radio frequency signal generated by a radio frequency signal source and sending the radio frequency signal respectively to a plurality of power amplifiers waiting to be tested as the input signal of the power amplifier. The high power attenuator module is used for decaying a multi-way signal exported by a plurality of power amplifier waiting to be tested and obtaining a multi-way detecting signal. The power detection module is used for coupling respectively the multi-way detecting signal and detecting a power value. The control circuit module is used for adjusting the input signal of the power amplifier, reading the power detecting value and saving the power detecting value. The method and the device provided by the present invention can greatly improve the detecting speed and efficiency in the power amplifier batch production on the condition that the instrument and the work station cost are not increased. At the same time a path is provided to the batch dynamic high temperature aging of the power amplifier.
