Research on the MAX038 Simulation Model for Electromagnetic Inspection

The high-frequency signal generator MAX038 is particularly suitable for RF signal sources of electromagnetic nondestructive testing, but the lack of finite element simulation model impedes the application of MAX038 in physical field simulation analysis. In this paper, we study the internal structure and principle of MAX038, divide its equivalent circuit architecture into different function modules, and then create and package its simulation model with modularization method. Based on the MAX038 simulation model, the RF excitation signal generator is designed and fabricated by using MSP430 processor, and an optimized detection algorithm is proposed to verify the simulation model. The test results of the MAX038 model and RF signal generator show that the MAX038 model proposed in this paper matches the real chip performance, it can also meet the requirements of simulation analysis for the parameter coupling relationship between electromagnetic field and defects.
