Transmission line characteristics

Click For Summary
SUMMARY

The discussion centers on calculating the primary coefficients R (resistance), L (inductance), C (capacitance), and G (conductance) for a transmission line operating at 250 MHz with a characteristic impedance (Z0) of 50 Ohms and a propagation coefficient (γ) of 0.4 + j7.5 per meter. Participants express confusion over the formulas required for these calculations. The Wikipedia article on transmission lines is recommended as a valuable resource for understanding the necessary concepts and formulas.

PREREQUISITES
  • Understanding of transmission line theory
  • Familiarity with characteristic impedance (Z0)
  • Knowledge of propagation coefficients (γ)
  • Basic electrical engineering principles
NEXT STEPS
  • Study the formulas for calculating primary coefficients R, L, C, and G in transmission lines
  • Review the Wikipedia article on transmission lines for foundational knowledge
  • Explore practical applications of transmission line theory in RF engineering
  • Learn about the impact of frequency on transmission line characteristics
USEFUL FOR

Electrical engineering students, RF engineers, and professionals involved in the design and analysis of transmission lines will benefit from this discussion.

Homework Statement


If a transmission line operating at 250 MHz has a characteristic impedance Z0 of
50 Ohm and propagation coefficient γ = 0.4 + j7.5 per meter, calculate its primary
coefficients R, L, C and G.

Hello, I do not know what formula I can use to solve this problem.
If anyone can give me some help it would be much appreciated.

What learning resources are you provided for this course? It seems strange that they would assign you this question, without having first presented the material to you...

In any case, the Wikipedia article on transmission lines is pretty good:
