The XU1019-QH upconverter is a gallium-arsenide (GaAs) monolithic microwave integrated circuit (MMIC) spanning 37 to 40 GHz. It integrates an image-reject balanced mixer, local-oscillator (LO) buffer amplifier, LO doubler, and RF buffer amplifier within a fully molded 4-x-4-mm QFN package. The upconverter offers an input third-order intercept point of +20 dBm. It boasts conversion gain of 7 dB and image rejection of greater than -15 dBc. The device can be tuned to give 2 x LO leakage of less than -25 dBm.

In addition, variable-gain regulation can be achieved by adjusting the bias with turn-down trajectories that are optimized to maintain linearity and minimal 2 x LO leakage over the gain control range. The XU1019-QH is well suited for point-to-point (PTP) radio, LMDS, satcom, and VSAT applications. Engineering samples are available from stock with a lead time of 14 weeks for production quantities.
