摘要
论述了一种无线数据链系统的射频前端设计方式,所涉及的数据链系统满足地面站工作人员进行回路控制,可以实现单一地面站控制8个飞行终端。为实现上述目的,设计了一种性能稳定、针对性强的硬件收发平台。简要介绍了模块功能,阐述了设计方案和硬件实现,进行了电路测试,该平台通过与基带信号处理板卡连接,并通过工控机控制界面进行人机交互。测试结果表明,该平台基于正交低中频整体架构,信号传输有效、稳定。
The article discusses the design approach of a RF front-end for wireless data link system.The system requires ground staff to monitor and control 8 missile-borne terminals.The system designs a stable, specialized transceiver hardware platform which could be connected through the baseband signal processing boards. Human-computer interaction is provided through IPC control interface. Based on the overall structure of low-IF architecture,we first introduce the function module briefly,then describe the design of a hard- ware implementation, and finally test the circuit to ensure the signal could transmit effectively and reliably.
