###### Question details

A transmission line has the following per-unit-length parameters: L = 0.5 µH/m, C = 150 pF/m, R = 13.0 Ω/m, and G = 0.02 S/m.

Calculate the propagation constant and characteristic impedance of this line at 800 MHz. If the line is 25 cm long, what is the total attenuation in dB? Recalculate these quantities in the absence of loss (i.e., R = G = 0).
