Receiver and transmitter MMICs complete first 38GHz SMT chipset

Mimix Broadband Inc of Houston, TX, USA has launched surface mount technology (SMT) packaged, gallium arsenide monolithic microwave integrated circuit (MMIC) receiver and transmitter devices that cover the 35-45GHz and 36-42GHz frequency bands, respectively.

The XR1008-QB receiver integrates an image-reject mixer, an LO doubler/buffer amplifier, and a low-noise amplifier and is offered in a 7mm x 7mm SMT package. The XU1006-QB transmitter integrates a balanced, image-reject mixer, an LO doubler/buffer amplifier, and an output RF amplifier consisting of a series of gain and attenuation stages to achieve linear gain control with a fixed IF input level.

The image-reject receiver has a noise figure of 3.5dB and 10dB conversion gain with +5dBm IIP3. The transmitter has a +17dBm output OIP3 and 5dB conversion gain across the band.

The receiver/transmitter pair is suited to wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications.

The devices come in 7mm x 7mm QFN surface-mount laminate packages. “The receiver and transmitter pair, along with our XP1031-QK power amplifier, complete the industry’s first 38GHz SMT chipset,” claims product manager Paul Beasly. “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.”
