4.5 - 10.5 GHz
Integrated LNA, Mixer and LO Buffer Amplifier
1.8 dB Noise Figure
13.0 dB Conversion Gain
Lead-Free 4 mm 24-lead QFN Package
100% RF, DC and NF Testing
RoHS* Compliant and 260°C Reflow Compatible
The XR1008-QB is a 4.5-10.5 GHz QFN packaged
receiver that has a noise figure of 1.8 dB and 13.0
dB conversion gain across the band. The device
integrates an LNA, image reject mixer and LO buffer
amplifier within a fully molded 4x4mm QFN package.
The image reject mixer eliminates the need for a
band pass filter after the LNA to remove thermal
noise at the image frequency. I and Q mixer outputs
are provided and an external 90 degree hybrid is
required to select the desired sideband. This device
uses M/A-COM Technology Solutions’ GaAs pHEMT
device model technology, and is based upon
electron beam lithography to ensure high
repeatability and uniformity. This device is
specifically designed for Point to Point radio
applications and is well suited for other telecom
applications such as SATCOM and VSAT.
