DESCRIPTION AND APPLICATIONS
The Filtronic Solid State LMA419 is a low noise PHEMT amplifier that operates from 18 to 22GHz.
This 3-stage reactively matched amplifier provides 22dB nominal gain with 2.5dB typical noise
figure and saturated power output of +5dBm The LMA419 is designed for commercial mm-W
(millimeter-wave) PCN/PCS applications. Ground is provided to the circuitry through vias to the
backside metallization.
