The only options to satisfy this first rule is add a capacitor, Option #1, or an inductor, Option #2, in series to move the impedance \(z\) along the \(r=0.4\) circle until meeting \(g=1\) circle at points O1-S1 & O2-S1.įig. 8, we can simultaneously read the impedance \(z\) and admittance \(y\) of point X:įollow the first basic rule of impedance matching, add a lossless element, capacitor or inductor, to get the real part of either impedance or admittance to be 1. 8 Type #2 impedance in the Smith chartĪs showed in Fig. Locate the impedance \(z=r+jx\) in the Smith chart, point X.įig. If the impedance is \(Z=R+jX\), then the normalized impedance is \(z=Z/50=r+jx\).ģ.

If return loss \(S_\) or reflection coefficient \(Γ\) is given by datasheets, then refer to this article Smith Charts-Basics, Parameters, Equations, and Plots to learn how to convert the number to impedance.Ģ. The process to match a Type #1 impedance into 50Ω:ġ. Type #1 impedance is located within the area of \(r=1\) circle. Matching Type #1 impedance: r ≥ 1, x any value.

For my class, I have been trying to plot constant resistance and reactance curves on the Smith chart.
