一种应用于车载系统的GPS接收机射频前端的设计

The design of RF Circuit in GPS receivers applies in the car- mounted system

无线应用技术包括全球定位系统(GPS)等已经获得了巨大的发展,利用GPS技术进行导航定位,无论是在军用或民用领域,都有着广泛而重要的应用价值。而在整个无线应用系统中射频电路的设计起到了举足轻重的作用。本文在概述了现有GPS接收机的基础上,讨论了一种应用于车载系统的GPS接收机的前端部分设计,并重点对其中的射频电路进行了设计与分析。

The wireless technologies including the Globle Posi- tioning System have achieved a great development, utilizing the GPS technology to proceed the navigation and direction has a extensive and important application value. The RF design has placed a great impact in the whole wireless system. Based on the GPS Receivers, the emphasis of this thesis is to design and assay the RF Circuit which applies in the car-mounted systems.
