| Mimix Broadband, Inc. Introduces 10 to 18 GHz SMT Packaged, GaAs MMIC Sub-Harmonically Pumped Receiver and Transmitter Chipset
Receiver Delivers 2.7 dB Noise Figure, and Transmitter Achieves +11 dBm P1dB
 September 20, 2007, Houston, Texas - Mimix Broadband, Inc. introduced
today surface mount technology (SMT) packaged, gallium arsenide (GaAs)
monolithic microwave integrated circuit (MMIC) receiver and transmitter
devices that cover the 10 to 18 GHz frequency bands. The receiver has a
noise figure of 2.7 dB and 20 dB image rejection across the band. The
transmitter has a +11 dBm output P1dB, 8 dB conversion gain and 15 dB
image rejection across the band.
The receiver integrates an image reject mixer, an LO buffer amplifier,
and a low noise amplifier. The transmitter integrates a balanced,
image-reject mixer, an LO buffer amplifier, and an output RF amplifier.
The image reject mixer eliminates the need for an image bandpass filter
after the amplifier to remove thermal noise at the image frequency.
This receiver and transmitter pair, identified as XR1007-QD and
XU1005-QD respectively, is well suited for wireless communications
applications such as millimeter-wave point-to-point radio, local
multipoint distribution services (LMDS), SATCOM and VSAT applications.
 "The combination of very low noise figure and high input third order
linearity in the XR1007-QD receiver offers excellent performance for a
wide variety of applications that require both high levels of
sensitivity and power-handling capabilities," stated Paul Beasly,
Product Manager. "The XU1005-QD transmitter integrates a balanced,
image-reject mixer that also enhances LO to RF isolation along with
power-handling capabilities. These two devices offer high levels of
integration in SMD technology, thereby providing a high-performance,
cost-effective solution for our customers' design requirements."
Mimix performs 100% RF and DC testing on these products. The devices
come in a 7x7 mm QFN surface mount laminate package, offering excellent
RF and thermal properties, and the packages are RoHS compliant.
Engineering samples and production quantities are available today from
stock. Technical support is also available from Mimix's applications
engineers at 281.988.4600. The datasheets and additional product
information can be obtained from the Mimix Broadband website at www.mimixbroadband.com .
