Mimix Broadband, Inc. Introduces 38 GHz SMT Packaged, GaAs MMIC Sub-Harmonically Pumped Receiver and Transmitter Chipset

Receiver Delivers 3.5 dB Noise Figure, and Transmitter Provides Linear, Variable Gain

January 25, 2008, 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 35 to 45 GHz and 36 to 42 GHz frequency bands, respectively. The image-reject receiver has a noise figure of 3.5 dB and 10 dB conversion gain with +5 dBm IIP3. The transmitter has a +17 dBm output OIP3 and 5 dB conversion gain across the band.

The receiver integrates an image reject mixer, an LO doubler/buffer amplifier, and a low noise amplifier and is offered in a 7x7mm SMT high performance package. The transmitter integrates a balanced, image-reject mixer, an LO doubler/buffer amplifier, and an output RF amplifier. The RF amplifier is comprised of a series of gain and attenuation stages to achieve linear gain control with a fixed IF input level.

This receiver and transmitter pair, identified as XR1008-QB and XU1006-QB 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 receiver and transmitter pair, along with our XP1031-QK power amplifier, complete the industry's first 38 GHz SMT chipset," stated Paul Beasly, Product Manager. "By offering highly integrated devices in surface mount packaging technology, we enable our customers to greatly simplify their designs and improve time-to-market at a lower cost."  

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 .
