摘要 |
In a surface acoustic wave device for removing narrow band signals, detection sensitivity is significantly improved by disposing a group of metal strip arrays on the side opposite to output transducers with respect to input transducers on the surface of a piezo-electric film and connecting a group of diode arrays with this group of metal strip arrays. |
