Question A-007-002-001

What kind of impedance does a quarter wavelength transmission line present to the source when the line is shorted at the far end?

Correct Answer

A very high impedance

Explanation

A shorted quarter-wavelength (λ/4) transmission line acts as an impedance inverter; it transforms a short circuit (zero impedance) at the far end into an open circuit (very high impedance) at the input.
