Title:
ELASTIC SURFACE WAVE RESONATOR
Document Type and Number:
Japanese Patent JPS5397391
Kind Code:
A
Abstract:
The input and output transducers associated with an acoustic surface wave resonator, or with respective acoustically coupled cavities, are split into staggered pairs. Furthermore they are located with respect to the standing wave pattern(s) and connected to input and output terminals in such manner as to suppress the response of the output transducer to travelling waves received directly from the input transducer and reduce the stopband level of the device associated with that response.
