Quarter-wave transformers (separate page) What's so special about a quarter-wavelength? Here is a clickable index to our material on quarterwave transformers: How do you turn a short circuit into an open circuit, or a capacitor into an inductor? Here we will describe some of the magic that happens when you use the distributed properties of transmission lines, in particular when you use lines of length one-quarter wavelength, or multiples of a quarter-wavelength.
