ABSTRACT:
A thin-film BAW filter has at least one CRF section and at least one ladder or grating filter section, with the CRF section having at least two coupled resonators, with the CRF section and the ladder or grating filter section being integrated on a common substrate, in order to produce a thin-film BAW filter. In a method for production of a thin-film BAW filter, having at least one CRF section and at least one ladder or grating filter section, the CRF section has at least two coupled resonators and the CRF section and the ladder or grating filter section are integrated on a common substrate.
