专利汇可以提供Acoustic surface wave filter专利检索，专利查询，专利分析的服务。并且A surface-wave integratable filter includes an input transducer for launching acoustic surface waves along a path in a propagating medium. An output transducer responds to those surface waves by developing output signals. One or both transducers takes the form of an iterative series of conductive ribbons disposed laterally across the path. The ribbons are spaced apart by a distance of one-fourth the wavelength of the acoustic waves. The input or output signals are coupled across adjacent pairs of successive ribbons with the center-to-center distance between such adjacent pairs being one-half the wavelength.，下面是Acoustic surface wave filter专利的具体信息内容。

权利要求

1. In an acoustic-wave transmitting device having an acousticwave-propagating medium, a first transducer responsive to input signals for launching along a predetermined path in said medium desired acoustic surface waves exhibiting a predetermined wavelength and a second transducer responsive to said desired acoustic waves for developing output signals and also responsive to triple-transit acoustic-surface waves also of said wavelength in said medium for developing undesired output signal components, the improvement in at least one of said transducers comprising: an iterative series of conductive ribbons individually disposed on said medium across said path and laterAlly spaced one from the next by a center-to-center distance of one-fourth said predetermined wavelength; and means for coupling signals across adjacent pairs of said successive ribbons, the center-to-center distance between said adjacent pairs being one-half said predetermined wavelength.

2. A device as defined in claim 1 in which said coupling means includes a first conductive strip disposed on said medium and connecting together the ribbons in one of said adjacent pairs, and a second conductive strip disposed on said medium and connecting together the ribbons in the other of said adjacent pairs.

3. A device as defined in claim 2 in which said first conductive strip is located along one side of said path and said second conductive strip is located along the opposite side of said path.

4. A device as defined in claim 1 in which said one transducer presents a predetermined impedance and which further includes an external load connected across said transducer that exhibits an impedance significantly lower than said predetermined impedance.

5. A device as defined in claim 1 in which said one transducer presents a predetermined impedance and which further includes an external source connected across said transducer that exhibits an impedance significantly lower than said predetermined impedance.
