一种高度集成化导航接收机系统射频电路的设计与实现
Design and Realization of RF Circuit of a Highly-Integrated Navigation Receiving System
摘要
Abstract
This paper introduces the realization method of a kind of highly integrated navigation receiver to achieve the goal of many modules miniaturization integration.The system includes DC/DC power supply module,low noise amplifier module,frequency conversion module,and so on.Limited in 168 mm×118 mm area of PCB area,integrated with the 28 V to 5 V power supply modules with small ripple and high quality;the RF link whose noise coefficient is less than 2.6 and the gain is about 100 dB the sensitivity of GPS navigation receiver is-130 dBm.Through actual hardware debugging,each module function is good and it can be used as a general platform for the passive navigation receiver.The system has a high level of integration,security is good,the advantage of high reliability which can be used in the small satellite and other emerging areas.At present the scheme products have been in a satellite orbit flight,performance well.关键词
