Abstract:
The present invention provides a surface acoustic wave filter, comprising: an interdigital transducer, two reflectors disposed opposite to each other on two sides of the interdigital transducer, and a plurality of parameterization units integrated on the interdigital transducer and the two reflectors. The overall performance of the filter is improved by arranging the two reflectors to be opposite to each other on two sides of the interdigital transducer, and by integrating the plurality of parameterization units on the interdigital transducer and the two reflectors.
