The invention relates to a filter with a first partial filter (TF), comprising a series resonator (S) and at least two parallel resonators (P, P) that are arranged in respective parallel branches, and with a second partial filter (TF) 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 (DL, DL) guided within the base plate. At least two lines for connections to ground of the first parallel resonator (P) and the second partial filter (TF) are guided separately in or on the base plate and are connected to at least two different external housing contacts (E, E).

RF-filter with improved adjacent channel suppression

An electrical component has electrically conducting structures placed on an electrically isolating or semiconductive substrate and component structures sensitive to a voltage or an electrical arcing and galvanically separated from one another. To prevent an arcing between the galvanically separated component structures, the component structures are short-circuited with a shunt line having a smaller cross-section than the remaining electrical conductor tracks. The shunt lines can be burnt through by application of an electrical current at any given time, whereby a galvanic separation of the component structures is effected, if necessary, for the function of the component.
