LMA420
LOW NOISE PHEMT MMIC
• DESCRIPTION AND APPLICATIONS
The Filtronic Solid State LMA420 is a low noise PHEMT amplifier that operates from 21 to 24GHz.
This 3-stage reactively matched amplifier provides 22dB nominal gain with 3dB typical noise figure
and saturated power output of +5dBm The LMA420 is designed for commercial mm-W (millimeter-
wave) PCN/PCS applications. Ground is provided to the circuitry through vias to the backside
metallization.
