Mimix Broadband's 10.0-18.0 GHz GaAs MMIC transmitter provides +17
dBm output third order intercept and 15 dB image rejection across the
band. This device is an image reject, balanced mixer followed by a two
stage output amplifier. The image reject mixer reduces the need for
unwanted sideband filtering before the power amplifier. I and Q mixer
inputs are provided and an external 90 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.
