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.
