tool to generate Smith Charts



A Smith chart is a tool used in electrical engineering that shows how the complex impedance of a transmission line varies along its length, and simplifies the design of impedance matching networks to match the line to its load.

linSmith is a Smith Charting program, mainly designed for educational use. As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation.

It's main features are:

  • Definition of multiple load impedances (at different frequencies)
  • Addition of discrete (L, C, parallel and series LC, and transformer) and line components (open and closed stubs, line segments)
  • Connection in series and parallel
  • Easy experimentation with values using scrollbars
  • A 'virtual' component switches from impedance to admittance to help explaining (or understanding) parallel components
  • The chart works in real impedances (not normalized ones)
  • Direct view of the result on the screen
  • Ability to generate publication quality Postscript output
  • A 'log' file with textual results at each intermediate step
  • Load and circuit configuration is stored separately, permitting several solutions without re-defining the other
