摘　　要：简明阐述了声表面波(SAW)器件的一些应用和新发展,并例举了表贴SAW射频、中频滤波器在北美CDMA/PCS双模制式终端内的典型应用,分别对比了国内外供应商推向CDMA系统的SAW 69.99 MHz和114.99 MHz中频滤波器及终端Rx用881.5 MHz SAW射频表贴滤波器的性能指标,并提出了一些意见和看法。This paper demonstrates some applications and new developments of SAW devices. Some typical applications, like incorporating surface mounting SAW filters of radio or intermediate frequencies into CDMA/PCS terminals are illustrated. The performance indexes of 69.99 MHz/114.99 MHz IF filters and 881.5MHz radio frequency filters are contrasted between native producer and overseas supplier. The author＇s own opinion and viewpoint are hence proposed.
