Definition of "Impedance Matching" |
The connection of an additional impedance to an existing one in order to accomplish a specific effect, such as to balance a circuit or to reduce reflection in a transmission line. The matching of impedances from one circuit to another to insure optimum power transfer. / In electronics, impedance matching is the practice of designing the input impedance of an electrical load or the output impedance of its corresponding signal source to maximize the power transfer or minimize signal reflection from the load. / Ultraviolet are electromagnetic radiation having a wavelength shorter than that of the violet end of the visible spectrum but longer than that of X-rays. / (1) one of the main design activities in microwave circuit design. An impedance matching network is made up of a combination of lumped elements (resistors, capacitors, and inductors), or distributed elements (transmission lines of varying characteristic impedance and length). Impedance matching networks transform network impedance from one value to another. |
