Parasitic feedback is prevented in a transmitter, a modulator, or a demodulator from having an interfering influence on the circuit section that generates the mixed frequency. The circuit has a main oscillator and a subordinate oscillator connected downstream of the main oscillator. The main oscillator generates a signal having an xth harmonic that serves to excite the subordinate oscillator. Furthermore, a frequency divider is connected downstream of the subordinate oscillator. The frequency divider divides the frequency of an output signal of the subordinate oscillator by an integer divider value. The divider value differs from the value x.
