Mimix Broadband, Inc. has released 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, all within a fully molded 4x4mm QFN package. This 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. The XU1012-QH is well suited for point-to-point (PTP) radio, LMDS, SatCom and VSAT applications. The XU1012-QH is 100% RF and DC tested.
