Abstract
The modulation includes in amplifying the microwave signal phase shifted by a given angle into a first sinusoidal signal, in order to obtain a first amplified signal; and in amplifying the microwave signal phase shifted by the given angle increased by π into a second sinusoidal signal phase shifted by π with respect to the first signal, in order to obtain a second amplified signal phase shifted by π with respect to the first amplified signal; the modulated microwave signal being the sum of the first amplified signal and the second amplified signal.
