4 results about "Smith chart" patented technology

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, Sₙₙ scattering parameters, noise figure circles, constant gain contours and regions for unconditional stability, including mechanical vibrations analysis.
