DESCRIPTION AND APPLICATIONS
The LMA442 is a medium power pHEMT amplifier that operates from 26.5 to 29.5 GHz. This 3-
stage amplifier provides 19 dB linear power gain with 1-dB gain compression power output of
greater than +22 dBm. The LMA442 is designed for LMDS/LMCS applications. Ground is provided
to the circuitry through vias to the backside metallization.
