Annotation: The design of 1-2 GHz single- and double-stage LNAs on PCB is demonstrated using the genetic-algorithmbased software tool Geneamp that provides the structural-parametric synthesis of microwave transistor amplifiers. The new approach, implemented in Geneamp, allows synthesis of the microwave transistor amplifiers using sets of S-parameters. The approach allows generating the schematics according to real performance of chosen manufacturer’s components. The comparison of modeled and measured performances of LNAs is presented.
