Abstract
An oscillator/mixer circuit having a reduced area requirement when producing it on a chip and where the circuit's mixer circuit is not based on the use of the nonlinear characteristic curve of an active component. The preferred embodiment of the oscillator/mixer circuit comprises an oscillator circuit; a mixer circuit, wherein the oscillator and mixer circuits have the same components to some extent and wherein the mixer circuit has at least a first switch element and a second switch element. An output of the first switch element is coupled to a control input of the second switch element via a first feedback element. An output of the second switch element is coupled to a control input of the first switch element via a second feedback element. The feedback elements are set up allow oscillator operation of the oscillator/mixer circuit.
