高可靠大时带积声表面波卷积器

A Stable SAW Convolver with Large Time Bandwidth Product

一种采用小孔径换能器、多抽头波导的简洁有效的设计的卷积器获得了较好的性能。该器件具有２０％以上的相对带宽和２５．６μｓ的互作用时间，设计充分考虑了技术指标和可靠性要求，使器件能满足严格的工作条件。

A good performance SAW convolver was designed using small aperture transducer and multi tapped waveguide.Its relative bandwidth>20%,interrection time is of 25.6 μs.The specifications and stabilities of the devices were considered thoroughly in the design,so as to meet the rigorous operating conditions and lay the foundation for the devices in wide applications.
