General Description
Mimix Broadband’s 35.0-42.0 GHz GaAs transmitter is an integrated
multifunction chip which provides 25 dB of linear gain control across
the band. The MMIC has a +17.0 dBm output third order intercept
across the band.This device is a balanced, resistive pHEMT mixer
followed by a series of cascaded gain and attenuator stages. The
device also includes an integrated LO doubler and LO buffer amplifier
which make the provision of the LO easier than for fundamental mixers
at these frequencies. 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
