摘要： 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.

摘要： A reactance filter includes a series branch that includes a number of series impedance elements that are coupled in series and a number of parallel branches each having a parallel impedance element coupled to a respective node of the series branch. Each impedance element includes a resonator that works with acoustic waves. The resonators in the series branch include a first piezoelectric material and the resonators in the parallel branches include a second piezoelectric material that is different than the first piezoelectric material.
