一种新型信标机的设计与实现

根据无线电数据链系统及部件的调试需要,研制开发了一种新型的以锁相环为核心、由单片机控制的射频信标机;文中给出了基于锁相环芯片PE3336的新型信标机的设计方法与系统组成,阐述了系统硬件及软件的具体实现方法;测试结果表明,利用该方法设计的信标机具有稳定、可靠的变频特性,且各项指标均达到了要求;进一步在某无线电系统中的应用发现,用户可方便地设置所需频点;特别是友好的人机界面,使用户操作更为灵活方便,是一种性能价格比优良的信标机;并可作为信源用于不同的射频部件研制与调试过程中.

Design and Accomplish of a Novel Beaconing

Based on the requisition of wireless system debugging,this paper develops a novel radio-frequency beaconing.Design method and system constitution of a novel beaconing based on PLL IC PE3336 are given,and the accomplish method of the system's hardware and software are expounded.The test results show that the beaconing adopted in this method has a reliable and stable frequency conversion features.The more applications in the wireless system find that the users can set necessary frequency conveniently.Especially,the friendly man-machine interface makes the operation is more flexible.It is an excellent performance-price-ratio beaconing,and as a signal source,it can be used in the research and the debug procession of variable radio-frequency components.
