Quadrature Demodulators
The QD series quadrature demodulators directly convert an RF input to differential I and Q baseband outputs.
Internally matched lowpass filters provide I and Q anti-aliasing for high-speed A/D converter interfacing.
Excellent linearity, amplitude imbalance, and quadrature phase error enable high-performance direct conversion receiver applications.
