This button allows you to change the font for the plot. The interactive Smith chart enables users to navigate their way around a Smith chart, using simple discrete element impedance matching. TRANSMISSION LINES To understand the Smith Chart, the theory of electric waves.
In Smith charts you can select the radius to be either linearly scaled, db-scaled or voltage-standing-wave-ratio-scaled. The Smith chart appeared in 1939 as a graph-based method of simplifying the complex math (that is, calculations involving variables of the form x + jy). The Smith chart 33 2.1 Impedance and Reflection Charts 33 2.2 Conformal. 0 10 0.2 50 zj Z L j Z + + impedance VSWR 1.55 1 R. Example 1: 50 Wline connected to 75+j10 Wload impedance. The VSWR is read where the circle crosses the real axis on the right side. Draw a circle centered on the Smith chart that intersects this point. In polar plots, the radius unit is the same as in the current plot. Plot the normalized load impedance on the Smith chart. Opens a dialog which allows you to enable or disable a background circle with a given radius. Min, Max: Allows you to specify the minimum and the maximum frequency values that are used when the polar plot or the Smith chart is plotted.Īuto range: Enables or disables automatic scaling to the maximum frequency range. Tick: Allows you to specify the ticking of the radial axis.Īuto tick: Enables or disables automatic ticking for the radial axis. This tool is javascript so it works on Windows, Mac, IOS, Android.
SMITH CHART FREE
Logarithmic: Enables or disables logarithmic scaling for the radial axis. This free online interactive Smith chart tool is a calculator which can help you design matching networks and obtain maximum power transfer between your source and load. Round: Enables or disables round scaling for the radial axis. Min, Max: Allows you to specify the minimum and maximum radial axis values that are used for the polar plot.Īuto range: Enables or disables automatic scaling for the radial axis range. Tick: Allows you to specify the ticking of the angular axis.Īuto tick: Enables or disables automatic ticking for the angular axis. These options are available for polar plots only. In this dialog, you can modify the view of the polar plot or Smith chart. Given an output impedance of 50ohms, use a Smith chart to calculate the reflection coefficients for the following impedances: (a) 100 angle 0deg, (b). Smith Chart and Polar Plot Properties Smith Chart and Polar Plot Properties View > Plot Properties. Smith chart is considered as a graphical measuring tool which is constructed mainly for electrical engineers to solve problems related to RF transmission lines.
