MACOM’s 34.0-46.0 GHz GaAs MMIC fundamental image
reject mixer can be used as an up- or down-converter.
The device has a conversion loss of 7.0 dB with a 20.0
dB image rejection across the band. I and Q mixer
outputs are provided and an external 90 degree hybrid
is required to select the desired sideband. This MMIC
uses MACOM’s 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.
