Surface acoustic wave filter










Image Number 5 for United States Patent #4829273.

A frequency characteristic of a surface acoustic wave filter having at least a first transducer and a second transducer is determined by a product of a frequency amplitude characteristic of the first transducer and that of the second transducer so that the electrodes of the both transducers are formed in such a way that third harmonics band in the frequency characteristic of the first transducer is shifted out that of the second transducer in order to prevent third harmonics.
