Impedance Matching: Formula, Circuit & Applications

WitrynaUsing stubs is a well-known method for impedance matching circuits. A stub is an opened or short-circuited line of suitable length used as a reactance shunted across the transmission line, of characteristic impedance Zc, at a calculated distance from the matched load of impedance ZL. Witryna19 paź 2001 · A single stub tuneruses a piece of transmission line(the stub) connected in seriesor parallelwith the main transmission line to match a load. By matching the load impedanceto the transmission line's characteristic impedance, we can avoid reflections and other signal degrading nastiness. A similar way to match impedancesis by using WitrynaTuning stubs are segments of open-ended or short-ended transmission lines that are used for distributed impedance matching.
