摘　　要：卫星导航产业、通信产业、互联网产业三者之间具备一定的技术关联性,其在技术层面各有侧重点,三者之间能够很好地实现互补、融合和增值,并且能够对人们的日常生活和国民经济发展起到积极的促进作用。本文深入研究了北斗导航系统第一代RDSS终端射频接收电路,重点研究了低噪声放大器和变频混频器的功能设计,并利用仿真软件进行了模拟实验测试。实验结果表明,本文所设计的噪声放大器和混频器性能优异,均达到了预期的设计要求。The satellite navigation industry,the communication industry and the Internet industry have a certain degree of technical relevance,and each has its own emphasis on the technical level. The three industries can complement,integrate and add value,and play a positive role in promoting people’s daily life and national economic development. In this paper,the RF receiving circuit of the first generation RDSS terminal of the Beidou navigation system is studied in depth,and the functional design of the low-noise amplifier and the frequency converter mixer is emphatically studied,and the simulation experiment is carried out by using the simulation software. The experimental results show that the noise amplifier and mixer designed in this paper have excellent performance and meet the expected design requirements.
