  • DMS filter with improved matching
    Patent number: 7915975
    Abstract: For improving the matching of a DMS track that is connected in series with a reactance element, it is proposed to connect a shunt branch to ground between the DMS track and reactance element parallel to the signal-carrying conductor section, where a capacitive element is arranged in this shunt branch.

  • Electrical Multiband Component
    Publication number: 20080186106
    Abstract: An electrical multiband component includes at least three signal paths, each for the transmitting signals in a corresponding frequency band. A frequency-separating filter includes an input side and an output side. The input side is electrically connected to an antenna path and the output side is electrically connected to the signal paths. A bandpass filter includes a double mode surface acoustic wave (SAW) filter in at least one of the signal paths.
