![]() ![]() The Inverse Smith chart is a circular chart on which the measured complex reflection coefficients ( Sii, where a value from 1 to N is taken, N is a number of Analyzers) are compared with the normalized DUT admittance. Smith chart properties Inverse Smith Chart (Complex Admittance) SMITH CHART IMPEDANCE AND ADMITTANCE SERIESThe Smith chart format is useful for looking for mismatch introduced by parasitic elements connected in series with the DUT. Use the Smith chart to assess circuit mismatch and determine whether the load is resistive, inductive, capacitive, or complex. The u nit circle diagram corresponds to an unmatched circuit with total reflection | | = 1. The center of the diagram corresponds to a matched circuit with no reflect signal ( = 0). Thus, any circle with the center coinciding with the center of the diagram contains equal values of the modulus of the reflection coefficient.
