The HMC340LP5 is a double-balanced dual mixer covering 1.7 - 4.5 GHz RF/LO range. This passive MMIC mixer is constructed of GaAs Schottky diodes and on-chip baluns. The device can be used as an upconverter, downconverter, biphase (de)modulator, or phase comparator. The mixer symmetry of the HMC340LP5 makes it an ideal candidate for single sideband or image rejection applications. The consistent MMIC performance will improve system operation and assure regulatory compliance. A low cost, leadless 5x5 mm QFN surface mount package (LP5) houses the dual MMIC mixer IC.
