Mimix Broadband's 36.0-40.0 GHz GaAs MMIC receiver has a typical small signal conversion gain of 5.0 dB with a typical noise figure of 4.0 dB and 12.0 dB typical 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 17.0-21.0 GHz. The image reject mixer removes 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 m 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.
