Mimix Broadband Inc. has introduced surface-mount technology (SMT) packaged, gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) receiver and transmitter devices that cover the 10 GHz to 18 GHz spectrum. The receiver exhibits 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 comprises an image reject mixer, a 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 the XR1007-QD and the 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 where both high levels of sensitivity and power-handling capabilities are required.

The XU1005-QD transmitter integrates a balanced, image-reject mixer that also enhances LO-to-RF isolation along with power-handling capabilities.
The devices are housed in 7 mm x 7 mm QFN surface-mount laminate packages, offering excellent RF and thermal properties, and the packages are RoHS compliant.

Engineering samples and production quantities are available now from stock.
