Abstract:
An acoustic wave filter having reduced non-linearities as well as a production method are disclosed. A filter comprises a first electroacoustic transducer having a first metallization ratio and a second electroacoustic transducer having a second metallization ratio. The metallization ratios range from 0.2 to 0.8, and the metallization ratio of the first transducer is no more than 0.8 times the metallization ratio of the second transducer.
