#MATLAB SMITH CHART CODE#

smithplot (frequency,data) creates a Smith chart based on frequency and data values. Use Grid to change the grid to YZ on the Smith plot. data nport ( 'default.s2p' ) smithplot (data) Right click on the S11 line to reveal interactive menu, DISPLAY.

Plot the Smith plot of S-parameters data file, default.s2p.

I haven't found any hints or examples that could help me at least. The Smith chart is commonly used to display the relationship between a reflection coefficient, typically given as S11 or S22, and a normalized impedance. Use the Smith plot interactive menu to change grid type of the Smith plot. s = SmithPlot(gamma) īut how do I mark the VSWR circle and the reflection angle in the same Smith Chart including the information text? I don't think the help in MatLab is very helpful in this regard sadly. The lengths of the through and stub lines are typically found using the Smith Chart (b), where through and. Gamma has the format of a single complex number (like 0.298 + 0.315i). Figure 4: (a) A shorted shunt stub matching network. I have found that this works for plotting the zL (normalized load impedance) via the reflection coefficient, gamma (calculated from ZL and Z0). Plot(x,y) % Reflection angle from origo through zL

= smithchart(gamma) % Graph of normalized impedance Input and output stability circles lays outside of smith chart, which means that amplifier is unconditionally stable or stable with all source and load. Vswrcirc = gammaAbs*cos(circ) + 1i*gammaAbs*sin(circ) įigure('Position',)

I need to convert from SmithChart to SmithPlot in this snippet of code in a MatLab file: if license('test','rf_toolbox') % Check for RF-toolbox
