These devices are described in some detail herein since it is through its terminations alone that the transmission characteristics of waves along any given waveguide can be controlled. Slug transformers, on the other hand, are sections of line of appropriate characteristic impedance (or characteristic admittance) and length connected in series with, and forming a continuation of, the main line. Matching stubs or building-out sections, as they are sometimes called, are sections of transmission line, frequently of the same characteristic impedance (or characteristic admittance) as that of the main line, and either open or short-circuited at their far end, connected in shunt with the main line at any one of several permissible positions in the general location where it is desired to provide the match. These include the single and the dual matching stub, and the single and the dual matching slug transformers. Several commonly used devices for obtaining a match at the load end of a transmission line will be described in this chapter.

SMITH CHART PDF SOFTWARE
This edition includes a new chapter with example designs and description of the winSMITH software accessory. The text provides tutorial material on transmission line theory and behavior, circuit representation on the chart, matching networks, network transformations and broadband matching. This classic reference book describes how the chart is used for designing lumped element and transmission line circuits.
It covers the history, development and applications of the Smith Chart. Smith, the originator of the Smith Chart. This is the second edition of Electronic Applications of the Smith Chart, written by Phillip H.
