Automatic 3-D Modeling of Integrated Power Amplifier by APDL

Aiming at the disadvantages of complexity and low efficiency of the traditional finite element modeling, the ANSYS Parameter Design Language(APDL) modeling is used to realize the automatic 3-D modeling of a GaN monolithic microwave integrated circuit (MMIC) PA in this paper. By executing the APDL program, the 3-D model can be constructed in few seconds. The modeling results show that this method only takes 47 seconds and 49 KB for modeling, comparing to the traditional method, which needs about several hours. Furthermore, it can overcome the shortness of time-consuming and resource-consuming for the finite element analysis(FEA). Meanwhile, it is convenient for model revision and important for the interconnect reliability analysis, which facilitates the automatic 3-D modeling for MMIC.
