声表面波器件至今尚未在古老的电讯领域获得广泛的应用,这可能是由于SAW器件通常不易满足电讯设备的严格要求,因而通讯技术人员一旦介入这一领域,就会使自己处于不太有利的地位的缘故。虽然如此,仍然有可以利用SAW器件的现有性能的一些专门的电讯应用,而且这些现有性肯能可以用得当的设计方法加以改进。本文即介绍这些应用的几个例子以及有关的设计方法。
SAW devices have so far not been widely used in the field of old telecommunications. This may be due to the fact that SAW devices are not always easy to meet the stringent requirements of telecommunications equipment, so communication technicians, once involved in this area, will be in a less favorable position Status of the reason. Nevertheless, there are still some specialized telecommunications applications that can capitalize on the existing capabilities of SAW devices, and these advances can be improved with the right design methodology. This article describes a few examples of these applications and related design methods.
