- 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.
