Low - noise microwave amplifiers 2ELU010 – 2ELU023

This series of low-noise microwave GaAs Schottky-barrier FET amplifiers with high input power limiters overlaps the frequency range from 0,8 to 3,6 GHz with minimum gain 23 dB and is designed for use in phased arrays of military and civil radar units.
