Question A-007-002-003

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

Correct Answer

A very high impedance

Explanation

A half-wavelength (λ/2) transmission line acts as a 1:1 impedance repeater; it presents the same impedance at its input as the load impedance at its far end. So, an open circuit remains an open circuit (very high impedance).
