Mimix Broadband introduces 5.6 to 10.5 GHz GaAs MMIC up-converter

Mimix Broadband Inc of Houston, TX, USA has introduced a 5.6 to 10.5 GHz GaAs MMIC up-converter that integrates a double balanced image reject mixer, LO buffer amplifier, RF buffer amplifier and variable attenuator.

Designed for point-to-point (PTP) radio, LMDS, SatCom and VSAT applications, the XU1012-QH RoHS-compliant, packaged up-converter has an output third order intercept point (OIP3) of +25 dBm, a conversion gain of 8 dB and a typical image rejection of 15 dBc. Variable gain regulation can be achieved by adjusting the bias, with turn-down trajectories optimized to maintain linearity and minimal 2xLO leakage over the gain control range, say the firm.

“The XU1012-QH is an ideal solution for lower side band, or LSB up-conversion in the 6 GHz and 7 GHz point-to-point ETSI radio bands,” said David Richardson, product line director, Mimix Broadband Inc. “The device has an optimal combination of high linearity, high image rejection, and low LO leakage, and is offered in a low-cost, industry standard 4x4mm QFN package.”

XU1012-QH is 100% RF and DC tested. A small quantity of engineering samples is available now, with a lead time of 14 weeks for production quantities.
