An improved digital data modulator is provided for a digital transmitter. The digital data modulator comprises of a pair of digital data synthesizers which are controlled in a manner which produces complex conjugate modulated data signals of the input signals. Summing means are provided to sum the outputs of the digital data synthesizers in a manner which removes the imaginary components and simultaneously reduces the side load power without employing conventional filters.
