<p>The invention relates to a system of converting signals with phase-shift-keying (PSK) modulation into signals with amplitude-shift-keying (ASK) modulation, said system comprising a power divider PDIV. A PSK signal is injected at the input of the aforementioned power divider at a frequency 2f, wherein f is half of the frequency of a carrier signal. Moreover, the power divider comprises an even number M of outputs at which corresponding signals i1..iM of equal frequency and phase are obtained, said outputs being connected respectively to M argument dividers with a natural lockable resonance frequency Div1..DivM, thereby obtaining M output signals O1..OM from said dividers. Furthermore, the invention comprises M-1 power combiners PC1..PCM-1 and the inputs thereof are connected in pairs to said M output signals O1..OM. In this way, signals with ASK modulation are supplied at the output of the M-1 power combiners, said signals responding respectively to each of the M-1 possible phase changes for said PSK input signal.</p> |
