Abstract:
A duplexer has an antenna terminal, a first terminal, and second terminals and provided with a first filter arranged between the antenna terminal and first terminal and including a parallel resonator for forming a ladder type filter circuit, a second filter arranged between the antenna terminal and the second terminal and having a passband higher than a passband of the first filter, and an electromagnetic coupling element arranged between the parallel resonator of the first filter and a ground part and electromagnetically coupled with the antenna terminal.
