DESCRIPTION AND APPLICATIONS
The Filtronic Solid State LMA246 is a high gain low noise PHEMT amplifier that operates from 9 to
14GHz. Reactively matched 3-stage amplifier provides 28dB nominal gain with 2dB typical noise
figure and 1-dB gain compression power output of +17dBm that can be used as a pre-driver
amplifier for phased array radar as well as commercial communications applications. Ground is
provided to the circuitry through vias to the backside metallization.
