Abstract:
    A transmitting arrangement includes a matching circuit (20), a reference circuit (60) and a comparator (1). The output of the matching circuit (20) can be coupled to an antenna (5) and comprises an adjustable impedance (26). The reference circuit (60) is connected to an input (61) of the matching circuit (20) and comprises a reference impedance (66). Inputs of the comparator (1) are coupled to the matching circuit (20) and the reference circuit (60) and its output is coupled to the adjustable impedance (26) via a control input (30) of the matching circuit (20).
