  • FILTER DEVICE COMPRISING TWO CONNECTED FILTER CIRCUITS
    Publication number: 20220255529
    Abstract: A filter device having a reduced sensitivity to production tolerances comprises a multilayer panel with integrated wiring, a piezoelectric substrate mounted to the panel. A first filter circuit (FC1) and a signal path (SP) comprising a second filter circuit are realized on the substrate and connected to a common antenna terminal (AT) as well as to a common node (CN) located on top of the piezoelectric substrate. A first matching circuit (MC1) and further matching circuits (MC2) are realized by the wiring in the multilayer panel.
