Description
The Filtronic LMA184 is a GaAs monolithic distributive amplifier which operates from 2 to 18GHz. This LMA184 amplifier produces a typical
gain of 7.5dB and a noise figure of less than 5.5dB. The LMA184 is suitable for gain block, low noise and driver amplifier applications. DC
decoupled output RF port. Ground is provided to the circuitry through vias to the backside metallization.
