Mimix Broadband, Inc. Introduces 17 to 25 GHz SMT Packaged, GaAs MMIC, Sub-harmonically Pumped Receiver and Transmitter Chipset

Single Chip Devices Integrate Image Reject Mixer, LO Buffer and Amplifier in QFN Package

December 20, 2006, Houston, Texas - Mimix Broadband, Inc. introduced today surface mount technology (SMT) packaged, gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC), sub-harmonically pumped receiver and transmitter devices. These chips integrate an image reject sub-harmonic anti-parallel diode mixer, an LO buffer amplifier and a low noise amplifier for the receiver, and an output amplifier for the transmitter. The image reject mixer eliminates the need for an image bandpass filter after the amplifier to remove thermal noise at the image frequency. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, these devices cover the 17 to 25 GHz frequency bands. The receiver has a noise figure of 2.5 dB and 20 dB image rejection across the band. The transmitter has a +23 dBm output third order intercept point (OIP3) and 15 dB image rejection across the band. This receiver and transmitter pair, identified as XR1006-QD and XU1002-QD respectively, are well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications.

"This receiver and transmitter pair is ideally suited for 17.7-19.7 GHz PDH microwave radio applications, with image rejection, +2 dBm LO drive level and low noise figure in the receiver. The high level of integration, along with true surface mount packaging allow customers to lower their material and assembly costs and improve their time to market," stated Paul Beasly, Product Manager, Mimix Broadband, Inc.

Mimix performs 100% on-wafer RF and DC testing on these products. The devices come in a 7x7 mm QFN surface mount package, offering excellent RF and thermal properties, and the packages are RoHS compliant.

Engineering samples and small production quantities are available today from stock production. Technical support is also available from Mimix's applications engineers at 281.988.4600.
