ZL = load impedance.
Zi = input impedance at the input of quarter wave transformer.
The above two have to be matched, so that what should be the characteristic impedance of QWT.
We have, Zo^2 = sqrt(ZL * Zi).
Therefore, Zo = 100 Ω.

ZL = LOAD IMPIDENCE.
ZI = INPUT IMPIDENCE.
ZO = CHARACTERSTICS IMPIDENSES.
ZI = INPUT IMPIDENCE.
