U1009-BD
Mimix Broadband’s 18.0-36.0 GHz GaAs MMIC transmitter has a +25.0
dBm output third order intercept across the band. This device is a
balanced resistive pHEMT mixer followed by a distributed amplifier
and includes an integrated LO doubler and LO buffer amplifier. The use
of integrated LO doubler and LO buffer amplifier makes the provision
of the LO easier than for fundamental mixers at these frequencies. IF
and IF mixer inputs are provided through an external 180 degree
hybrid. 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.
