Abstract: An example of a device for generating a broadband frequency signal comprises a first controlled oscillator, a second controlled oscillator, a phase-locked loop for feeding back an output signal of a controlled oscillator to the corresponding controlled oscillator, and a mixer. The mixer is configured to generate the broadband frequency signal by mixing an output signal of the first controlled oscillator and an output signal of the second controlled oscillator. The device may, for example, be realized by means of a single phase-locked loop. A further example relates to a device for generating a frequency signal with a controlled oscillator and a phase-locked loop with a further controlled oscillator and a mixer in the feedback path of the phase-locked loop. Examples further relate to a high-frequency device for emitting a high-frequency signal and a method for generating a broadband frequency signal.
