A fully molded QFN packaged, gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) receiver that covers the 4.5 to 10.5 GHz frequency bands.
The highly integrated receiver has a noise figure of 1.8 dB and 13 dB
conversion gain across the band.
The receiver, identified as XR1011-QH, integrates an image reject mixer, an LO buffer amplifier, and a low noise amplifier within a fully molded 4x4mm QFN package that is RoHS compliant.
The image reject mixer eliminates the need for an image bandpass filter after the amplifier to remove thermal noise at the image frequency. The XR1011-QH is well suited for wireless communications applications such as millimeter-wave
point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT.
“The XR1011-QH is the industry’s first fully molded 4x4mm QFN packaged receiver covering the frequency range of 4.5 to 10.5 GHz,” stated Paul Beasly, Product Manager. “This part is also distinguished by its impressive performance, combining low noise figure, high conver
