Smith Charts were originally developed around 1940 by Phillip Smith as a useful tool for making the equations involved in transmission lines easier to manipulate. See, for instance, the input impedance equation for a load attached to ...
WebThe admittance form of the Smith chart is used in the following example. Example 14.6.1. Single Stub Matching. In Fig. 14.6.6a, the load admittance Y L is to be matched to a transmission line having characteristic admittance Y o by means of a "stub" consisting of a shorted section of line having the same characteristic admittance Y o.Variables that can … WebA Smith Chart is utilized by examining the load and where the impedance must be matched. Sometimes, instead of considering the load impedance directly, you express its reflection …
WebDetermining the SWR Produced by a Given Load A 50- line is terminated by a load impedance ZL = 50 + j35 . Determine the SWR produced by this load by drawing the corresponding SWR circle on the Smith Chart of Figure 11-5. 1. Normalize the load impedance and then plot this impedance on the Smith Chart (point marked "A" on the … WebThe following are some of the more important applications of the Smith chart: 1. Admittance calculations. This application is based on the fact that the impedance measured at Q is equal to the admittance at P, if P and Q are λ/4 apart and lie on the same SWR circle. This is shown in Figure 7-12. The impedance at Q is 1 – j1, and a very ...
