Question

One end of a loss-less transmission line having the characteristic impedance of 75 $Ω$ and length of 1 cm is short-circuited. At 3 GHz, the input impedance at the other end of the transmission line is

Open in App

Solution

Ans : (d)

It is a short circuit line with l = 1 cm

As $λ = \frac{3 \times 10^{8}}{3 \times 10^{9}} = 0.3 = 30 c m$

$l < \frac{λ}{4}$

The line has inductive nature.

As $Z_{S C} = k = j Z_{0} t a n β l$
