Keywords:transceiver? transmitter? receiver? Mimix? MMIC?

Mimix Broadband Inc. has introduced an SMT-packaged, GaAs 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?m gate length GaAs pHEMT device model technology, these devices cover the 17-25GHz frequency bands. The receiver has a noise figure of 2.5dB and 20dB image rejection across the band. The transmitter has a +23dBm OIP3 and 15dB 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.

Mimix performs 100percent on-wafer RF and DC testing on these products. The devices come in a 7-by-7mm 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.
