R1001

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 R1001 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 m GaAs PHEMT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity. The R1001 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. The R1001 is well suited for Millimeter-wave Point-to- Point Radio, LMDS, SATCOM and VSAT applications.
