Abstract: Harmonic rejection ability and reflection coefficient are the most important factors in the design of impedance matching network. However, dynamic stability of impedance matching should be taken into account in applications existing working frequency drift, load impedance variation and components deviation due to tolerances and process variation. In order to study the dynamic performance of T network impedance matching, theoretical analysis is conducted in accordance with the Q (quality)-based design method. The relationships between the matching result (reflection coefficient) and components deviation, load impedance variation and operating frequency drift are obtained. The analysis results suggest that higher Q value produces worse dynamic stability and that matching result is more sensitive to load impedance variation when the load reflection coefficient of static state is larger. In designing a T network, it is need to make the tradeoff between dynamic stabilit!
y and harmonic rejection ability. The analysis results provide theoretical basis for the design and characteristics analysis of T network impedance matching.
