Abstract:

The design of amplifier systems is greatly facilitated by the use of computers. An amplifying element is often represented by a linear two-port model, which is characterized by a set of s-parameters at a particular frequency or at a set of discrete frequencies. With the s-parameters, it is possible to plot loci of constant power gain and loci of constant imput impedance on a load-reflection-coefficient plane Smith Chart. With these plots, the designer can conveniently select the appropriate load to obtain the desired power gain and input impedance of the amplifier system at the frequency of interest. The HP9810 calculator and its associated plotter have been programmed to generate the above mentioned loci directly on a Smith Chart. The input data consists of only the s-parameters of the two port. These plots are simple and informative and can be obtained in a matter of minutes. Author
