中文摘要：
顺应双模或多模卫星导航接收机在民用市场中的发展趋势和需求，结合卫星导航接收机涉及的几个关键技术指标和射频电路设计的基本理论，采用两片MAX2769射频芯片，设计了一款北斗/GPS双模兼容的射频接收模组。实测结果表明，设计的模组性能优越，工作稳定，可以有效应用于商用卫星导航双模兼容接收机的研究中。
英文摘要：
In order to conform to the trends and needs of the dual-mode or muhi-mode of satellite navigation receiver in the civilian market, a dual-mode compatible RF receiver module of Beidou and GPS is designed using two MAX2769 RF chips. This design is based on the basic theory of several key technical indicators and RF circuits involved in the design of satellite navigation receiver. Experimental results show that this RF receiver module is superior performance and stable, which could be effectively ap plied to the dual-mode compatible navigation receiver of commercial satellite.
