User Documentation to Program PrCtLine
********
Calculations on Printed-Circuit Transmission Lines
==================================================
Program PrCtLine applies to striplines and microstrip lines, which
are printed on printed-circuit board and used primarily at microwaves.
Based on the material constants of the board, the program permits to
calculate
* the line width for a given characteristic line impedance ZL, or
* the characteristic impedance for a given line width.
In addition, the program permits the calculation of
* line attenuation,
* electrical line length.
The program considers all documented effects except microstrip
dispersion. Results are accurate up to 100 GHz for stripline and up to
25 GHz for microstrip.
All input data are interactively requested by the program during
execution. All user input is numeric; each number must be followed by
a carriage return (RET). A zero may be entered as a single RET.
The program requires an 8087-type coprocessor.
