| Zusammenfassung: | A duplexer and a quadplexer are disclosed. In an embodiment, the duplexer includes an antenna terminal and two sub-paths including a transmit path and a receive path, the two sub-paths being connected to the antenna terminal, wherein the transmit path includes serially interconnected series resonators and, in parallel therewith, n parallel paths connected to ground, wherein each parallel path includes one parallel resonator or a cascade of serially interconnected parallel resonators, wherein n is an integral number with 0 |
