Abstract: A signal modulation device comprises a delta-sigma modulator disposed for transforming an amplitude-modulation signal in baseband into a pulse signal. It also comprises a phase modulator receiving, at its input, analogue phase-modulation signals in baseband. The pulse signal is mixed with carrier signals upstream of the phase modulator. The modulation device is designed to form an input stage of a transmitter.
