Patent ID: 6975165

Claim:
A system for phase shift keying (PSK) signal conversion employing digital amplitude shift keying (ASK), characterised because it consists of a power divider, PDIV, with an entrance which is injected with a PSK signal at a frequency of 2f, where f is half the frequency of a carrier signal and with an even number, M, of outputs, from which the corresponding signals i 1 . . . i M are obtained at equal frequency and phase, respectively connected to M dividers with natural tuneable resonant frequency of Div 1 . . . Div M , obtaining M output signals O 1 . . . O M from these same dividers and M-1 power combiners PC 1 . . . PC M-1 , the inputs of which are connected two by two to the said M output signals, providing at the output of these power combiners, M-1 signals with ASK modulation, which respectively correspond to each of the possible M-1 phase changes of this PSK input signal.
