Impedance detection and voltage/current phase detection circuits are proposed, including their working principles and debugging methods, thus to realize the corresponding relationship of between the test data of network detection and the Smith chart region for subsequent judgment in tuning range. Accord-ing to the hardware matching network and the principle of Smith impedance chart, an in-depth exploration on the technical difficulties of this algorithm is done, and meanwhile the implementation scheme of imped-ance matching software design also presented. Test experiment indicates that the,average tuning time, tun-ing precision and other indexes could fairly meet the predefined requirements.
