The invention relates to a behavior level modeling and verification method of a power amplifier underlying circuit. The method comprises the following steps: S1: establishing a power amplifier underlying circuit model, and collecting the input signal and the output signal of a power amplifier as experimental data; S2: establishing a behavioral model based on a mathematical expression, and utilizing the experimental data for distinguishing the behavioral model; S3: establishing the same input signal exciting circuit, and calculating a normalized mean square error between the output signal of the power amplifier underlying circuit model and the output signal of the behavioral model; and S4: judging whether the normalized mean square error meets accuracy requirements or not, verifying the accurate description of the input / output characteristics of the power amplifier underlying circuit by the behavioral model, and regulating the behavioral model again until the normalized mean square error meets the accuracy requirements if the normalized mean square error does not meet the accuracy requirements. By use of the method, the problem that the power amplifier underlying circuit is complex in direct simulation solving is solved, the method can be applied to a simulation situation that the detail information of the underlying circuit is not completely known due to technical security, and an effective means is provided for the system-level electromagnetic compatibility analysis of a simulation and digital mixing circuit.
