Patent ID: 7230484

Claim:
RF signals amplification block for cooperating with a central processing unit, wherein said block comprises two channels for processing the first RF signal, said block comprising: means for amplifying a first RF signal, comprising first and second amplification means arranged respectively on the first and second processing channel so as each to deliver a third, amplified, RF signal of the same power, means for measuring the power of the third, amplified, RF signal, means for coupling the third amplified RF signals and being able to deliver on a second output a difference signal corresponding to the difference of said third signals and on a third output a sum signal corresponding to the sum of the third signals to a first output of the block as to deliver a second, amplified, RF signal or a signal to the means for measuring, depending of a control signal generated by the central processing unit as a function of the comparison between the power of the amplified RF signal and a nominal power value, the coupling means being associated with means to permute the second and third outputs.
