What is Transcalc?

Transcalc is an analysis and synthesis tool for calculating the electrical and physical properties of different kinds of RF and microwave transmission lines.

Transcalc was somewhat inspired by the functionality of Agilent Technologies' commercial program linecalc. Transcalc aspires to be more functional in the long run and well-documented with appropriate references to formulas that are used. Transcalc is built using the GIMP toolkit (GTK) for its GUI interface.

For each type of transmission line, using dialog boxes, you can enter values for the various parameters, and either calculate its electrical properties (analyze), or use the given electrical requirements to sythesize physical parameters of the required transmission line.

Available transmission lines (this list will expand with subsequent releases):


Transcalc uses the Gtk+ widget set. As of version 0.14, transcalc requires the gtk 2.0 development headers and library.

No GNOME packages are required.


Here is an obligatory screenshot showing the apprearance of transcalc for calculating parameters of a microstrip transmission line
