Abstract This electronic apparatus comprises a power amplifier formed by an output stage (21) that has a non-linear amplification characteristic, and a correction assembly (60, 46) for compensating for the non-linearities of said characteristic. This assembly is formed by a low-power preamplifier (46) of the same type as said power stage, consequently presenting the same non-linearity as stage (21). The combining device (60) combining the signals applied to the input terminal (25) with the output signals of said preamplifier (25) largely counteracts the non-linearities of said characteristics.
