Abstract
The invention describes a filter arrangement as well as an electronic component, each with a bulk acoustic wave resonator unit which is present on a carrier substrate ( ). A reflection element ( ) is provided between the carrier substrate ( ) and the bulk acoustic wave resonator unit for the purpose of acoustic insulation of the generated oscillations. This reflection element ( ) may consist either of several layers of alternately high and low impedance or, if the acoustically reflecting substance has a sufficiently low impedance, of a single layer. In addition, a mobile telephone device, a transmitter, a receiver, and a wireless data transmission system as well as a method of manufacturing an electronic component are described.
