XU1019-QH Delivers +20 dBm IIP3 and 7 dB Conversion Gain

Mimix Broadband’s 37.0-40.0 GHz GaAs MMIC Intergrated Up-converter that has a typical conversion gain of 7 dB, and an image rejection of greater than 15 dBc. It has been optimized for USB operation. The device includes a LO doubler and buffer, and can be tuned to give 2xLO leakage of less than -25 dBm. 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. At full gain, an IIP3 of 20 dBm is typical. The device comes in an RoHS compliant 4x4mm QFN surface mount package offering excellent RF and thermal properties. Typical application for this device are as an up-converter stage in a linear 38GHz radio transmit lineup. They device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
