To read off the VSWR on the line note the intercept of the VSWR circle with the right-half zero reactance line it is the horizontal line that bisects the top and bottom of the chart. Smith Charts 6 Suppose we have an initial admittance of y 02 - j05 And we add a shunt capacitor of y C j08. Complex Impedance Transformations Determining VSWR RL and much more Transmission Line impedance transformations Matching Network Design. The Smith chart is just a plot of complex numbers.

Z Z Z0. BW and colour smith and admittance charts. The impedance is represented by a normalized impedance z. The ratio of backwardforward wave.

The Smith chart lets us relate the complex dimensionless number gamma at any point P along the line to the normalized load impedance z L Z L Z o which causes the reflection and also to the distance we are from the load in terms of the wavelength of waves on the line. These could be admittance as well as impedance. Its deﬁnition as well as an introduction on how to navigate inside the chart are illustrated. Since w e an t to mo v a y from the load ie ard.

The normalized impedance is often used. Á L Á O à L F 4 E 4 L 7 E F 8 Here Z0 is the characteristic impedance of the transmission line or just some reference impedance for the Smith Chart. The Smith Chart 4 Smith Chart. It also allows the calculation of the admittance Y 1Z of an impedance.

Once around the circle is a line length of l2. We can then read off the normalized impedance z L at the. Smith Chart Problems 1. 3769 KB for free.

The Smith Chart The Smith Chart allows easy calculation of the transformation of a complex load impedance through an arbitrary length of transmission line.

Points on that circle represent impedance on the line corresponding to distance which is read from the scale wavelengths toward the. This paper will give a brief overview on why and more importantly on how to use the chart. Y C j08. Many of these web sites also present a deeper theoretical and less abbreviated historical explanation of the Smith chart.
