ABSTRACT:
A radiofrequency transmitting device delivers output signals having a chosen radiofrequency from input data split up into complementary phase data and amplitude data. This device includes a radiofrequency reference oscillator for outputting a reference signal having a fixed radiofrequency reference, and a digital phase modulator for synthesizing the chosen radiofrequency from the fixed radiofrequency reference and for phase modulating the reference signal with the phase data, in order to produce an output signal having the chosen radiofrequency.
