General Description
Mimix Broadband’s 33.0-40.0 GHz GaAs MMIC receiver has a small
signal conversion gain of 9.0 dB with a noise figure of 4.0 dB and 12.0
dB image rejection across the band. The device is a two stage LNA
followed by a pair of sub-harmonic mixers, configured to form an image
reject mixer which requires an LO at 15.5-21.5 GHz. 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 a sub-harmonic mixer
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.
