Abstract
The present invention relates to a power servo-loop in particular for controlling a power amplifier, the loop comprising a detection circuit ( ) having coupling means ( ) for taking off RF signals, and a detection unit ( ) for delivering a detection signal (Vdet) partially representative of a first RF signal taken off by the coupling means. The detection circuit of the invention comprises, between the coupling means and the detection unit, detection control means ( ) for substantially eliminating an “interfering” second RF signal also taken off by the coupling means, such that the detection signal is entirely representative of the first RF signal.
