XR1005-QD

XR1005-QD Mimix Broadband's 19.0-26.0 GHz GaAs packaged receiver has a noise figure of 3.0 dB and 20.0 dB image rejection across the band. This XR1005-QD 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 XR1005-QD 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 device comes in a 7x7 mm QFN Surface Mount Laminate Package offering excellent RF and thermal properties and is RoHS compliant. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
