| Abstract: | Equipment level filter circuit of a certain aircraft avionics system plays an important role in the normal operation of the system. 28VDC power supply filter circuit is selected as a typical circuit, which is combined with PCB printed circuit board diagram to conduct field and road co-simulation based on CST. Finally, the common mode insertion loss and differential mode insertion loss of the filter circuit are tested by the vector network analyzer to verify the correctness of the field-circuit co-simulation and the actual test, and the influence of each type of electrical components on common mode insertion loss and differential mode insertion loss is obtained through experiment and simulation. |

| Keywords: | power filter circuit simulation insertion loss common mode differential mode |
