General Description
Mimix Broadband’s 32.0-45.0 GHz GaAs MMIC transmitter has a
+14.0 dBm output third order intercept across the band. This
device is a balanced, resistive pHEMT mixer followed by a
distributed output 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 and an external 180 degree hybrid
is required to select the desired sideband. 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.

recommended to keep channel temperature as low as
possible for maximum life.
