DDS Modulators
DDS-based modulation products are an alternative scheme to the more traditional transmit DAC approach for quadrature digital upconversion in modern communications systems. They provide I/Q modulation and agile upconversion functionality and can also be configured as single tone direct digital synthesizers or interpolating D/A converters.
