Zusammenfassung:A filter circuit providing improved attenuation, a filter having improved attenuation and a duplexer with improved isolation are provided. The filter circuit has a first and a second coupling conductor segment which couple an input port to a ground port or the filter's output port. The filter circuit can be realized in the filter. The duplexer can comprise the filter, especially as its transmission filter.
