A quarter-wave transformer is a transmission line segment used to match the impedance between two different transmission lines, ensuring maximum power transfer and minimizing reflections. It operates by being exactly one-quarter of the wavelength of the signal in length, transforming the impedance of one line to another through its characteristic impedance properties.

Impedance matching is the practice of making the output impedance of a source equal to the input impedance of the load to maximize power transfer and minimize signal reflection. It is crucial in electrical engineering, particularly in RF applications and audio systems, to ensure efficient energy transfer and optimal system performance.
