    Abstract: The invention relates to a VGA stage having a novel circuit configuration for amplifying/attenuating a differential input signal which is transmitted via a transmission line (H). The VGA stage comprises an operational amplifier (OPV 1 , OPV 2 ), which is connected as shunt feedback, for amplifying the input signal; a string of resistors (R 01 , R 01' ) for attenuating the signal; and a control device ( 2 ) for switching the string of resistors (R 01 , R 01' ).
