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.
