transcalc - 0.14-6 main

Transcalc is an analysis and synthesis tool for calculating the
electrical and physical properties of different kinds of RF and
microwave transmission lines.
.
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 synthesize physical parameters of the required
transmission line.
.
Available transmission lines (this list will expand with subsequent
releases): Microstrip, Rectangular Waveguide.
