摘要: Disclosed is a surface wave device comprising one transducer having its fundamental resonant frequency at subharmonic of the operating and second frequency. Both transducers respond to waves Only harmonic operated responds bulk Thus, signal coupled from other contains no noise generated by mode coupling.
