![]() ![]() The Smith chart has a wide range of applications in the field of electrical engineering. The admittance circles are drawn with respect to the normalized admittance axis, which is rotated 180 degrees with respect to the impedance axis. ![]() Moving to the right represents an increasing resistance, while moving to the left represents an increasing reactance.Īdmittance values are represented on the Smith chart using a similar set of circles, with constant conductance (G) and constant susceptance (B) circles. On the horizontal axis, the chart displays normalized impedance, with the center point representing a normalized impedance of 1. These circles intersect to create a grid that represents all possible impedance values. The Smith chart is composed of two sets of circles: constant resistance circles (R) and constant reactance circles (X). The chart’s primary purpose is to simplify the analysis and design of these circuits by providing a visual representation of impedance and admittance transformations. Smith in 1939 and has since become a fundamental tool for electrical engineers working with radio frequency (RF) and microwave circuits. The Smith chart is a graphical representation of complex impedance and admittance. Understanding the Smith Chart: A Powerful Tool for Electrical Engineers Explore the Smith chart, a vital tool for electrical engineers analyzing RF and microwave circuits, with an impedance matching example.
