LMA411

LOW NOISE PHEMT MMIC

• DESCRIPTION AND APPLICATIONS

The Filtronic Solid State LMA411 is a high dynamic range low noise PHEMT amplifier that

operates from 8.5 to 14GHz. Reactively matched 2-stage amplifier provides 18dB 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.

• ELECTRICAL SPECIFICATIONS @ TAmbient = 25°C

(VDD = +6.0V, ZIN = ZOUT = 50Ω)
