Question
Show that a loss-free line of characteristic impedance $Z_{0}$ and length $n \lambda / 2$ may be used to couple two high frequency circuits without affecting other impedances.
Step 1
A loss-free line is a transmission line that has no resistance or conductance. This means that no power is lost as the signal travels along the line. The characteristic impedance $Z_{0}$ of a loss-free line is a pure real number. Show more…

Show that a line of characteristic impedance $Z_{0}$ may be matched to a load $Z_{L}$ by a loss-free quarter wavelength line of characteristic impedance $Z_{m}$ if $Z_{m}^{2}=Z_{0} Z_{L}$. (Hint-calculate the input impedance at the $Z_{0} Z_{m}$, junction.)
Show that the input impedance of a short-circuited loss-free line of lenght $l$ is given by $$ Z_{i}=i \sqrt{\frac{L_{0}}{C_{0}}} \tan \frac{2 \pi l}{\lambda} $$ and by sketching the variation of the ratio $Z_{i} / \sqrt{L_{0} / C_{0}}$ with $l$, show that for $l$ just greater than $(2 n+1) \lambda / 4, Z_{i}$ is capacitative, and for $l$ just greater than $n \lambda / 2$ it is inductive. (This provides a positive or negative reactance to match another line.)
Show that the characteristic impedance for a pair of Lecher wires of radius $r$ and separation $d$ in a medium of permeability $\mu$ and permittivity $\varepsilon$ is given by $$ Z_{0}=\frac{1}{\pi} \sqrt{\frac{\mu}{\varepsilon}} \log _{e} \frac{d}{r} $$
