LMA421
LOW NOISE PHEMT MMIC
• DESCRIPTION AND APPLICATIONS
The Filtronic Solid State LMA421 is a low noise PHEMT amplifier that operates from 36 to 40GHz.
This 4-stage reactively matched amplifier provides 22dB nominal gain with 4.5dB typical noise
figure and saturated power output of +5dBm. The LMA421 is designed for commercial mm-W
(millimeter-wave) PCN/PCS applications. Ground is provided to the circuitry through vias to the
backside metallization.
