DESCRIPTION AND APPLICATIONS
The Filtronic Solid State LMA219B is a low noise PHEMT amplifier which operates from 7 to
11GHz. This 2-stage reactive matched amplifier produces very low figure of 1.4dB with an
associated gain of 19dB. The LMA219B is designed for phased array radar applications. DC
decoupled input and output RF port. Ground is provided to the circuitry through vias to the backside
metallization.
