Klaus Dahlfeld has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7729448
    Abstract: A frontend module includes a first and a second input for transmitted signals, an amplifier, a bypass line for bypassing the amplifier, an output and a switching unit. The switching unit either forms a signal path between the first input and the output, in which the amplifier or the bypass line is coupled, or forms a signal path between the second input and the output, in which the amplifier or the bypass line is coupled.

  • Publication number: 20070064663
    Abstract: A front-end module (101) has an input (6) for reception of transmission signals from an apparatus (3) for production of transmission signals, and an output (15) for outputting the transmission signals to an antenna (5). The module has further an amplifier stage (11) which is connected in the signal path between the first input (6) and the output (15), and has a bypass line (103) which can optionally be connected in the signal path, for bypassing the amplifier stage (11), with the amplifier stage (11) being switched off when a bypass line (103) is connected in the signal path.
