描述 The QM3040A is a quadrature (I/Q) modulator optimized for direct modulation of an RF carrier. Differential I and Q inputs are mixed with the local oscillator (LO) to produce a modulated RF output. Internally matched lowpass filters provide anti-alias functionality for removing Nyquist images and wideband noise when interfacing to high-speed D/A converters. For more information on interfacing the QM3040A to highspeed D/A converters and single-ended sources, please see Application Note 101A, “Driving the QM Series Quadrature Modulators.”
