声表面波器件在七十年代得到了迅速的发展,并且出现了一种新颖的频率合成技术——声表面波(SAW)频率合成器。它不仅具有常规的频率合成器优良的电气性能。而且结构紧凑、体积小、重量轻、耗电省,很适合应用于雷达、扩谱通讯、导航和其它机动性大的电子设备。是一种很有发展前途的频率合成技术。本文综述了各种SAW频率合成器的进展。
Surface acoustic wave devices developed rapidly in the 1970s, and a novel frequency synthesis technique, the SAW frequency synthesizer, emerged. It not only has the excellent electrical performance of a conventional frequency synthesizer. And compact, small size, light weight, low power consumption, it is suitable for radar, spread spectrum communications, navigation and other mobility of large electronic devices. It is a very promising technology for frequency synthesis. This article reviews the progress of various SAW frequency synthesizers.
