The parameters of a certain transmission line operating at ω = 6×108 rad/s are L = 0.35μH/m, C = 40 pF/m, G = 75 μS/m, and R = 17 Ω/m => α=0.0943 Np/m, β=2.2467 rad/m, λ=2.7966 m, Z0 =93.623-j3.6368
A 50-Ω load is attached to a 50-m section of the above mentioned transmission line, and a 100-W signal is fed to the input end of the line.
(a) Evaluate the distributed line loss in dB/m.
(b) Evaluate the reflection coefficient at the load.
(c) Evaluate the power that is dissipated by the load resistor.
(d) What power drop in dB does the dissipated power in the load represent when compared to the original input power?
(e) On partial reflection from the load, how much power returns to the input and what dB drop does this represent when compared to the original 100-W input power?
