FILTER, DUPLEXER AND MODULE |
| 摘要 |
A filter includes: one or more series resonators connected in series between an input terminal and an output terminal; one or more parallel resonators connected in parallel between the input terminal and the output terminal; a first inductor having one end connected to at least one of the input terminal and the output terminal; a second inductor having one end connected to a terminal near a ground of at least one of the parallel resonators; and a third inductor connected between a first node and the ground, the first node connecting the other end of the first inductor and the other end of the second inductor. |
