In a near field communication partner device (1) intended for the contactless transmission of digital data to be transmitted having a transmission circuit (2), the transmission circuit (2) comprises a modulation circuit (17) for the amplitude modulation of a carrier signal (CS), which modulation circuit (17) comprises a circuit stage (20, 20′) for producing a plurality of different resistance values (RW1, RW1′) that act on a signal output (TX1, TX2), which resistance values (RW1, RW1′) can be transformed, by means of a signal processing circuit (3) arranged to transform resistance values that belongs to the communication partner device (1), into transformed resistance values (RW2, RW2′), which transformed resistance values (RW2, RW2′) are responsible for damping a transmission coil (7) of the communication partner device (1) when modulated low-level carrier signal sections are generated in a modulated carrier signal.
