What does a quarter-wave transformer do?
A quarter-wave transformer is a simple impedance transformer which is commonly used in impedance matching in order to minimize the energy which is reflected when a transmission line is connected to a load.
What is meant by quarter wavelength?
A quarter-wavelength away from the open-circuit, the current and voltage oscillations are exactly the same as at a short-circuit, and vice versa. This reflects the fact that open circuit (Z=∞) is dual to short circuit (Z=0).
How does quarter wave matching work?
A quarter-wave impedance transformer is an impedance transformer that is useful in matching the real load impedance to the transmission lines. A quarter-wave impedance transformer is generally the transmission line of length equal to one-quarter of the guided wavelength (to match the impedance).
What is the importance of a quarter wave line?
A quater wave line may be considered as an impendence inverter because it can transform a low impendence in to a high impendence and vice versa. IMPEDANCE MATCHING: QUARTER WAVE TRANSFORMER.
