| Zusammenfassung: | A filter device includes a first substrate, a first input electrode and a first output electrode on the first substrate, a first ground electrode on the first substrate and receiving a ground potential, an electrically open portion in or on the first substrate, a second substrate mounted on the first substrate, a second input electrode on a surface of the second substrate and connected to the first input electrode, a second output electrode on the surface of the second substrate and connected to the first output electrode, a second ground electrode on the surface of the second substrate and connected to the first ground electrode, and at least one first functional electrode on the second substrate and disposed on a first connecting path connecting the second input electrode and the second output electrode. The open portion is connected to the first connecting path. |
