Power Transmisson Homework: TL, VSWR, & Impedance Calc.

Click For Summary
SUMMARY

The discussion focuses on calculating transmission line (TL) parameters, voltage standing wave ratio (VSWR), and input impedance for a 50-ohm transmission line terminated with a load of 50-j25 ohms. The source impedance is also 50 ohms, and the line length is 1/8 of a wavelength. Participants express uncertainty about the calculations, particularly regarding the use of absolute values in impedance and the potential application of a Smith Chart for simplification.

PREREQUISITES
  • Understanding of transmission line theory
  • Familiarity with impedance calculations
  • Knowledge of VSWR and its significance
  • Experience with Smith Chart for impedance matching
NEXT STEPS
  • Learn how to calculate input impedance for transmission lines
  • Study the principles of voltage standing wave ratio (VSWR)
  • Explore the use of Smith Charts for impedance matching
  • Review complex impedance and its representation in calculations
USEFUL FOR

Electrical engineering students, RF engineers, and anyone involved in transmission line analysis and impedance matching will benefit from this discussion.

Homework Statement



A source with 50 ohm source impedance drives a 50 ohm T-line that is 1/8 of a wavelength long, terminated in a load Z=50-j25 ohms. calculate TL, VSWR, and the input impedance seen by the source

Attempt to the Solution?

Same goes for your other post as well.
 
ok sorry about that, this is my attempt at this problem so far.

i am not sure if i take the absolute value of both the imaginary and real part of ZL or if i did the calculation for VSWR right, please check my work.

Would this problem be easier done with a Smith Chart, if so could someone walk me through that method?
