A device for damping cavity resonance effects in a multilayer carrier device, having a first conductive device for making available a reference potential layer of the carrier device; a second conductive device that is electrically insulated from the first conductive device for making available a voltage supply layer of the carrier device; and at least one discrete, lossy circuit component, which is connected between the first and the second conductive device and is dimensioned as a function of at least one cavity resonance of the carrier device. Also provides a method for damping cavity resonance effects in a multilayer carrier device.
