Abstract |
AB |
[EN] The invention relates to a re-configurable filter. <??>An object of the invention is, to provide a new and improved approach for providing an increased reconfiguration flexibility with regard to a filter, in particular to a bandpass-filter for different high-frequency or radio-frequency bands, in particular suitable for use within the transceiver of base stations and/or user terminals, such as handsets adapted to be used within these communication systems, by preferably simultaneously reducing undesirable parasitic influences. The invention proposes a reconfigurable multibandfilter, in particular adapted for filtering high-frequency and/or radio-frequency comprising at least two filters (f1, f2, f3) connected at their input ports in parallel (1) into a signal path, and at least one controllable switching means for individually connecting (2) respectively one of the filter output ports into said signal path with the other filter output ports disconnected from said signal path and in particular connected to ground (3). |
