摘要： A method is for reducing a DC component of an input signal transposed into baseband and being generated by a first frequency transposition stage starting from an initial signal and from a transposition signal. The method includes amplifying the transposed input signal in a first amplifier. The first amplifier receives at a DC offset compensation input, a compensation signal extracted from an output signal of a second amplifier subjected to a compensation of a offset DC voltage of the second amplifier. The method also included alternating between receiving at an input of the second amplifier, a first auxiliary signal from an auto-transposition of a transposition signal in a second frequency transposition stage and a second auxiliary signal from a transposition of the initial signal in the second frequency transposition stage with the transposition signal.
