宽带高速电台接收机的接收链路设计,需要满足高带宽、宽动态范围和优良的线性度。简述了宽带高速通信接收机的链路设计的核心技术,主要阐述了接收机链路中的射频前端、电调滤波器、中频处理等设计要点,并对自动增益控制(AGC,Automatic Gain Control)的控制策略、增益分配、控制算法、自动电平跟踪等进行了进一步的说明。最后结合实际应用,介绍该接收机链路设计的应用及其使用效果。
Broadband high-speed radio receiver receiver link design, need to meet the high bandwidth, wide dynamic range and excellent linearity. The key technologies of the link design of broadband high-speed communication receivers are briefly described. The design essentials of RF front-end, ESC, IF processing in the receiver link are mainly described. The AGC (Automatic Gain Control) ) Control strategy, gain distribution, control algorithm, automatic level tracking, etc. are further described. Finally, with the practical application, the application of the receiver link design and its effects are introduced.
