DESCRIPTION AND APPLICATIONS
The Filtronic Solid State LMA422 is a low noise PHEMT amplifier that operates from 26 to 30GHz.
This 3-stage reactively matched amplifier provides 22 dB nominal gain with 3dB typical noise figure
and saturated power output of +5dBm. The LMA422 is designed for commercial LMDS (Local
Multipoint Distribution Services) and Ka-band applications. Ground is provided to the circuitry
through vias to the backside metallization.
