Broadband driver circuit for driving voice and data signals, having a current dividing circuit ( 37 ), which divides a current generated by a current source ( 38 ), in a manner dependent on a voice and data signal present at a signal input ( 21 ), into two base currents (Ib 1, Ib 2 ) for driving a first driver transistor ( 39 ) and a second driver transistor ( 40 ), the two driver transistors ( 39, 40 ) being constructed identically.
