PHB 32565 23.12.77 ABSTRACT: The input and output transducers associated with an acoustic surface wave resonator, or with respec- tive 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 out- put 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 stop- band level of the device associated with that response. - 36 -
