WebbPlugging this back into the S11 equation, the final expression becomes: S11 = 2*V(Out) - 1 The resultant Smith chart when plotting this expression is displayed below. Note that this plot has been normalized to the source resistance of 50 ohms. The impedance plot starts approximately at the real, imaginary values of 1,0. WebbPlot the Smith plot of S11 of s-parameter data file using an impedance of 75 ohms. data = sparameters ( 'passive.s2p' ); s = sparameters (data,75); p = smithplot (s,1,1, 'GridType', 'ZY' ); Use the data cursor icon in the toolbar to insert a cursor on your smith plot chart. You now know the S11, VSWR, Impedance, and frequency values at that cursor. WebbIf you fix the length of the transmission line segment and vary the frequency, you will get a circular plot on the Smith chart that is equivalent to changing the line segment length at a fixed frequency. For example, in the Smith chart of the previous step, L = 37.5mm was fixed. S11 at 2GHz falls at the origin of the Smith chart. uoft search engines
