MAX1195
quadrature outputs, a local oscillator followed by sub-
sequent upconversion can generate the QAM signal.
The result is an in-phase (I) and a quadrature (Q) carri-
er component, where the Q component is 90° phase
shifted with respect to the in-phase component. At the
receiver, the QAM signal is divided down into its I and
Q components, essentially representing the modulation
process reversed. Figure 10 displays the demodulation
process performed in the analog domain, using the
dual matched 3V, 8-bit ADC MAX1195 and the
MAX2451 quadrature demodulator to recover and digi-
tize the I and Q baseband signals. Before being digi-
tized by the MAX1195, the mixed-down signal compo-
nents may be filtered by matched analog filters, such
as Nyquist or pulse-shaping filters which remove
unwanted images from the mixing process, thereby
enhancing the overall signal-to-noise (SNR) perfor-
mance and minimizing intersymbol interference.
