Computer Program for Smith Chart Design of Microwave Matching Networks Using Interactive Graphics.

Abstract

An experimental programme in the field of microwave transistor power amplifiers required study of the design of microstrip matching networks. The normal design process involving manual use of the Smith chart was potentially tedious and an alternative approach using interactive graphics was conceived. A computer program was developed which plots impedance data and transformations on a Smith chart display, performing calculations analytically at several frequencies simultaneously. The program was brought to the stage where it can be used as a tool for design of microwave matching networks from specification of terminating impedances to determination of microstrip mechanical dimensions. This Report describes the capabilities, facilities and operation of the program and gives examples of its use. (Author)
