T-Line Z
Transformation This program calculates the input Z of a lossless transmission line given the Z0, electrical line length, theta, and the load Z = RL +j XL. Units: ohms,degrees Enter Z0,Theta,RL and XL [<Enter>=Quit] ? _ |
 |
This program is very easy to use, just enter the four parameters asked for above, each separated by a comma, and press <Enter>.
As an example, consider a 50 ohm transmission line that is a quarter-wave, (90 degrees), long at its operating frequency. If the load impedance is 75+j10, what is the input impedance?
Input "50,90,75,10" at the prompt up above and then press <Enter>.
Here is the output calculation:
Rin = 32.751 ohms
Xin = -j4.367
