摘　　要：YMNU—8型SAW固定延迟线为中心频率60MHz,延迟时间50μs的折叠式延迟线.它利用通道变换器将延时通道折叠,实现了在有限尺寸的基片上制作长延迟线.本文详细的介绍了YMNU—8型SAW固定延迟线的结构设计与原理,以及参数计算和器件性能等.Mode YMNU-8 SAW fixed delay line is a folded delay line with its center frequency of 60MHz and delay time of 50μs. This long delay line is tealized on a substrat of limited dimension by folding the delay track with track converter. In this paper, the structure design, principles, parameters calculation and the performance of the device are described in detail.
