transmission line

Question

A load impedance (200 + j0) ΩΩ is to be matched to a 50ΩΩ lossless transmission line by using a quarter wave line transformer (QWT). The characteristic impedance of the QWT required is

Answer 1

For Quarter wave line transformer
\(Z^2_0\) = Z_in . Z_L
\(Z^2_0\) = 50 × 200
Z₀=100 \( \Omega\)
