19.0-26.0 GHz GaAs MMIC Receiver April 2006 - Rev 10-Apr-06 Features Sub-harmonic Receiver Integrated LNA, LO Buffer, Image Reject Mixer +2.0 dBm LO Drive Level 2.3 dB Noise Figure 20.0 dB Image Rejection 100% On-Wafer RF, DC and Noise Figure Testing 100% Visual Inspection to MIL-STD-883 Method 2010 Mimix Broadband’s 19.0-26.0 GHz GaAs MMIC receiver has a noise figure of 2.5 dB and 20.0 dB image rejection across the band. This device is a two stage balanced LNA followed by an image reject sub-harmonic anti-parallel diode mixer and includes an integrated 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 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.
