It was independently devised by Tōsaku Mizuhashi ( 水橋東作) in 1937, and by Amiel R. The Smith chart is now known as a 50 Smith chart. Ive drawn two transmission lines with standing wave. The reference impedance ZREF is chosen to be 50, the same as the characteristic impedance of the transmission line in the circuit. The voltage standing wave pattern is what causes of changes in impedance with transmission line length. If we are dealing only with impedances with non-negative resistive components, our interest is focused on the area inside the circle. Those with negative real parts map outside the circle. Complex numbers with positive real parts map inside the circle. ![]() The Smith chart (sometimes also called Smith diagram, Mizuhashi chart ( 水橋チャート), Mizuhashi–Smith chart ( 水橋スミスチャート), Volpert–Smith chart ( Диаграмма Вольперта-Смита) or Mizuhashi–Volpert–Smith chart), is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits. The first step is to plot the load ZL on a Smith chart and this is the Point L in Figures 3.4.13 3.4.15. The Smith chart is a mathematical transformation of the two-dimensional Cartesian complex plane. For other uses of the term Smith diagram, see Smith diagram (disambiguation).
