General Description
Mimix Broadband’s 30.0-46.0 GHz GaAs MMIC receiver has a noise
figure of 3.5 dB and 18.0 dB image rejection across the band. This
device is a three stage LNA followed by an image reject resistive
pHEMT mixer and includes an integrated LO doubler and LO buffer
amplifer. The image reject mixer eliminates the need for a bandpass
filter after the LNA to remove thermal noise at the image frequency.
The use of integrated LO doubler and LO buffer amplifier makes the
provision of the LO easier than for fundamental mixers at these
frequencies. I and Q mixer outputs 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.
