Abstract

A radar-based fill-level measuring device comprising at least one synthesizer circuit having a plurality of circuit components for producing phase controlled microwave signals for a travel-time measurement and at least three electrical potentials for supplying the synthesizer circuit, wherein the synthesizer circuit has at least three circuit groups. Each circuit component is associated with at least one circuit group, wherein each of the at least three circuit groups is fed by means of at least one potential difference between two of the at least three different potentials.
