Annotation: The design of 1.2-1.8 GHz 0.15 μm GaAs pHEMT MMIC low noise amplifier for GNSS receiver is presented. LNA is designed with using a software tool gMatch that provides the synthesis of matching and compensation networks (MCNs) based on genetic algorithm (GA). An approach to the structural and parametrical GA-based MCN synthesis is briefly described. The abilities of gMatch tool, amplifier design flow, and MMIC LNA performances are considered.
