The applicatcation of surface acoustic wave(SAW)devices in generating and processing signals has been become an active branch in electronics, since the SAW technology penetrated into electronics. It is proved experimentally that a nonlinear frequence modulation(N—FM)signal can be generated by N—FM SAW dispersive delay line(DL). The N—FM—DL can be implemented by a double dispersive structure(DD). In this article some results about the study of a SAW power series FM—DL(PFM—DL)with time—bandwidth product of 160 and fractional bandwidth of 32% are presented. Both the method of frequence spectrum evolution and the way of seeking new coefficient, designing DD—PFM—DL, have been suggested. Calculated and observed results of frequence spectra, self—correlation pulces and group delay curves of these DL have been shown. Generally speaking, thse methods will be also applied to design any N—FM—DL. However, it must be noted that it can be used only when the relation of Fourier transform between frequence domain and time domain(ie, the geometrical patten of Interdigital transnsducer)is kept.

自从声表面波(SAW)技术渗透入电子学领域以来,应用SAW器件产生讯号和处理讯号已成为电子学中的一个活跃分技。实践表明,非线性调频讯号能用非线性调频SAW色散延迟线产生。非线性调频SAW色散线也能够由双色散结构来实现。本文报道了对时带宽积为160,相对带宽为3%的冪级数调频SAW色散线的研究结果。提出了两种设计双色散结构(DD)的冪级数调频色散线(PFM-DL)的方法。给出了理论计算的和实验观察到的频谱、自相关脉冲、群延迟特性。一般说来,这些方法也适用于其他非线性调频色散线。要注意的是,只有频域和时域即叉指换能器的几何图形之间保持着福氏变换关系时才能运用这一方法。
