摘 要: 提出一种适用于微纳卫星的统一S波段测控通信一体化应答机的设计方案,重点介绍其中数字化的中频与基带信号处理模块解决方案。对系统的测试结果显示,系统的占用带宽为241kHz、发射杂散为-47dBc,转发延迟为2μs,其关键指标均能满足测控标准。 This paper presents a TT&C( Telemetry,tracking and command) and communication integrated design scheme of USB transponder for the micro-nano satellite application,placing emphasis on the digital design of the IF and base band signal pro-cessing module. The test result of this system shows that the occupied bandwidth of this system is 241kHz; the stray of transmission is-47dBc,and the latency of transponder is 2μs. These performances of the system satisfy the norms in TT&C standards.
