Info Smith chart ( From Wikipedia, the free encyclopedia )
The Smith chart , invented by Phillip H. Smith (1905 – 1987), is a graphical aid 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 Smith chart can be used to simultaneously display
multiple parameters including impedances , admittances , reflection coefficients ,
scattering parameters , noise figure circles, constant gain contours and regions for
unconditional stability , including mechanical vibrations analysis. The Smith chart is
most frequently used at or within the unity radius region.
