    摘要: The invention relates to a filter with a first partial filter (TF1), comprising a series resonator (S1) and at least two parallel resonators (P1, P2) that are arranged in respective parallel branches, and with a second partial filter (TF2) configured as a DMS filter. The filter also comprises a housing with a plurality of internal housing contacts (GKi) on a base plate that are connected to terminal areas on the substrate (SU) and external housing contacts (GKa), fewer than the internal contacts, that are connected to the internal housing contacts (GKi) via lines (DL1, DL2) guided within the base plate. At least two lines for connections to ground of the first parallel resonator (P1) and the second partial filter (TF2) are guided separately in or on the base plate and are connected to at least two different external housing contacts (E4, E2).
