General Description
Mimix Broadband’s two stage 21.0-24.0 GHz GaAs
MMIC power amplifier is optimized for linear operation
with a third order intercept point of +39.0 dBm. This
MMIC uses Mimix Broadband’s 0.15 µm GaAs PHEMT
device model technology, and is based upon electron
beam lithography to ensure high repeatability and
uniformity. The chip has surface passivation to protect
and provide a rugged part with backside via holes and
gold metallization to allow either a conductive epoxy
or eutectic solder die attach process. This device is well
suited for Millimeter-wave Point-to-Point Radio, LMDS,
SATCOM and VSAT applications.
