General Description
Mimix Broadband's three stage 27.0-33.0 GHz GaAs MMIC
power amplifier has a small signal gain of 21.0 dB with +35
dBm saturated output power. The device also includes
Lange couplers to achieve good input/output return loss.
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.
