General Description
Mimix Broadband’s two stage 4.0-11.0 GHz GaAs
MMIC buffer amplifier has a small signal gain of 23.0
dB with a +20.0 dBm P1dB output compression point.
The device also provides variable gain regulation with
adjustable bias. 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
Microwave and Millimeter-wave Point-to-Point Radio,
LMDS, SATCOM and VSAT applications.
