Abstract
An acoustic wave filter includes a substrate, a first resonator disposed on the substrate, a second resonator disposed on the substrate to be spaced apart from the first resonator, a connector electrically connecting the first and second resonators, and a variable capacitor formed in the connector to tune a pass band frequency of the acoustic wave filter.
Claims21
An acoustic wave filter comprising:
- a substrate;
- a first resonator disposed on the substrate;
- a second resonator disposed on the substrate and spaced apart from the first resonator;
- a connector electrically connecting the first and second resonators;
- and
- a variable capacitor formed in the connector to tune a pass band frequency of the acoustic wave filter.

A method for manufacturing an acoustic wave filter, the method comprising:
- forming a connector on a substrate;
- forming a variable capacitor in the connector;
- forming a first resonator and a second resonator on the substrate to be connected to the connector and be disposed on both terminals of the variable capacitor;
- and
- tuning a pass band frequency of the acoustic wave filter by applying a voltage to the variable capacitor.
2 more elements
An acoustic wave filter, comprising:
- a first resonator disposed on a substrate;
- a second resonator disposed on the substrate and spatially separated from the first resonator;
- and
- a variable capacitor electrically connecting the first resonator and the second resonator,
- wherein the variable capacitor is configured to have a capacitance dependent on a voltage applied across electrodes of the variable capacitor for tuning a pass band frequency of the acoustic wave filter.
