A quadplexer providing improved insertion loss and pass band steepness is provided. The quadplexer comprises a first filter structure with a first filter element, a second filter structure with a second filter element and an inductive element that is electrically connected in series between common ports of the filter structures and input ports of the filter elements.

Quadplexer and quadplexer component

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.
