专利汇可以提供Acoustic surface wave filters专利检索,专利查询,专利分析的服务。并且A body of piezoelectric material is capable of propagating acoustic surface waves and a first transducing device is coupled to a surface of the body to develop those waves. Spaced on the same surface from that first device is a second transducing device. The spacing is sufficiently small that crosstalk exists between the devices. To reduce the magnitude of that crosstalk, one or more of several different decoupling arrangements are included. These comprise the connection of diametrically opposite transducer electrodes to a common plane of reference potential, the connection of the mutually closest electrodes of the respective transducers to a plane of common reference potential, the disposition of one or more ground electrodes between the transducers and across the path of wave propagation, the development across the transducers of signals balanced with respect to such a plane, the physical shielding of the space generally above one of the transducers, the inclusion of a conductive shield on the surface opposite the wave-propagating surface and the formation of shielding channels in that surface opposite the wave-propagating surface. In addition, the wave propagation path advantageously is caused to be oriented at an angle relative to the end surfaces of the piezoelectric body in order to minimize reflected wave interference.,下面是Acoustic surface wave filters专利的具体信息内容。
