Quadrature Modulators
The QM series quadrature modulators are optimized for direct modulation of an RF carrier. Differential I and Q inputs are mixed with the LO input to produce a modulated RF output.
Internally matched lowpass filters remove Nyquist images and limit wideband noise when interfacing with high-speed D/A converters.
Excellent linearity, amplitude imbalance, and quadrature phase error enable high-performance transmitter applications.
