A computer-aided design approach is developed for the analysis and design of broad-band amplifiers with complex terminations, e.g., an antenna. The transfer scattering parameters are used for the analysis of a cascade connection of distributed lines and amplifiers. A modified version of Rosenbrock's minimization procedure is used to find the optimum lengths and characteristic impedances of the lines which minimize the reflection losses and realize a desired gain characteristic. Several examples are given.
