Abstract (en)
[origin: WO2016015914A1] A duplexer is proposed that can be used in quadplexers and in diverse carrier aggregation modes. Said duplexer comprises resonators in a ladder type structure, wherein at least one of the parallel resonators in the transmission path is connected to ground in series with an inductance, wherein the parallel resonator in the parallel path, which is closest to the antenna connection, is directly connected to ground and no inductance is arranged in the corresponding parallel path.
