Abstract

A frequency generator includes two voltage controlled oscillators, which have a plurality of switchable sub-bands, each, and which are designed to produce respective frequency signals, wherein a switching from one sub-band to a neighboring sub-band occurs at predetermined switching locations. The sub-bands of the second oscillator are arranged offset in frequency relative to the sub-bands of the first oscillator. The frequency generator includes an electronic switch element, which is designed to switch either the first or the second frequency signal through to the output of the electronic switch element, and to switch the switch element such that during the producing of the frequency ramp alternately either the first or the second frequency signal is switched through to the output. When at one of the oscillators the switching between two neighboring sub-bands is occurring, the frequency signal produced by the other oscillator is switched through to the output.
