1. A transmitter arrangement, comprising:

  • a first and a second controlled oscillator, each comprising a control input and a signal output;

    a first control device comprising a first data input, a first feedback input and a first control output which is coupled to the control input of the first controlled oscillator;

    a second control device comprising a second data input, a second feedback input and a second control output which is coupled to the control input of the second controlled oscillator;

    a first power amplifier comprising an input coupled to the signal output of the first controlled oscillator, an output coupled to the feedback input of the first control device and a first power control input to adjust a gain factor of the first power amplifier;

    a second power amplifier comprising an input coupled to the signal output of the second controlled oscillator, an output coupled to the feedback input of the second control device and a second power control input to adjust a gain factor of the second power amplifier; and

    a summation element which on its input side is coupled to the output of the first and the second power amplifier and which comprises an output coupled to a signal output of the transmitter arrangement;

    wherein the first feedback input is selectively coupled to the output of the first power amplifier or to the signal output of the first controlled oscillator depending on a feedback control signal, and wherein the second feedback input is selectively coupled to the output of the second power amplifier or to the signal output of the second controlled oscillator depending on the feedback control signal.
