LADDER-TYPE FILTER, DUPLEXER, AND MODULE |
| 摘要 |
A ladder-type 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; divided parallel resonators formed by serially dividing at least one parallel resonator of the one or more parallel resonators; and an inductor of which a first end is coupled to a first node located in a path from the input terminal to the output terminal through the one or more series resonators, and of which a second end is coupled to a second node located between the divided parallel resonators. |
