Abstract :
An optimisation program OPTIMAL is described which includes algorithms for dispersion and loss in microstrip. The optimisation routine combines pseudorandom and conjugate gradient pattern-search techniques to improve the chances of finding a global-minimum solution to multimodal problems. The optimisation of a GaAs f.e.t. amplifier shows the program´s ability to produce good results from poor starting values.
