Abstract :
Computer-aided pattern search has been applied to the optimisation of resistively terminated impedance transformers consisting of cascaded noncommensurate transmission-line sections. For prescribed impedance ratios and fixed numbers of sections, optimum transformer designs were found to be of the quarter-wave Cheby¿shev type, improvement over which does not seem likely.
