ELASTIC SURFACE WAVE FILTER

摘要

ELASTIC SURFACE WAVE FILTER of the Disclosure The filter according to the invention includes, on the surface of the plate, an emitting transducer, a surface wave coupler and means receiving the waves radiated by the coupler, including two transducers having a first common terminal used as a phase reference, the voltages of the second terminals of each transducer in relation to the common terminal being in phase opposition in the transmission band of the filter.
