A method is provided for manufacturing a saw filter in which a carrier plate that can be separated into base plates is respectively provided with interconnects in the base plate regions A and these are contacted to the active structures of SAW chips in flip-chip technique. A metal foil or plastic film is placed onto the chip-equipped carrier plate and, for example, is pressure and heat treated such that it envelopes each chip (except for the chip surface facing toward the carrier plate ) and lies hermetically tight on the carrier plate surface in regions between the chips.
