High-frequency module

Disclosed is a high frequency module for producing or processing radar signals for use in radar-based fill-level measuring devices. The high frequency module includes: a semiconductor component to produce or to process electrical, high frequency signals; a dielectric coupling element contacted with the semiconductor component to couple the high frequency signals as radar signals into a dielectric waveguide or in order to couple radar signals from the waveguide as electrical, high frequency signals into the semiconductor component. The coupling element and the waveguide form a plug contact. In the case of appropriate design of the plug contact there results upon plug-in a self-centering, so that need for a complex adjustment during manufacturing is absent. Since radar frequencies of above 100 GHz can be produced by the semiconductor component, corresponding fill level measuring devices are characterized by a high measuring resolution and compact structures.
