资料介绍

分析了AGC系统的结构和工作原理,介绍了压控放大器VCA810的性能特点。根据接收机信号调理特点,设计了一种基于VCA810的大动态范围自动增益控制电路,给出了AGC电路仿真结果,并详细介绍了电路的工作原理。实验结果表明,基于VCA810的AGC电路能够达到80dB动态范围的预期目标,并可以灵活调节输出电平值,保证接收机正常工作。

The system structure and working principle of AGC were analyzed in the paper, and the main functions and performance of the VGA (Variable Gain Amplifier) VCAS10 were introduced. Large dynamic range AGC circuit based on VCAS10 is designed for receiver signal conditioner circuit. We simu- late the AGC circuit, and introduced the working principle in detail. The experiment shows that the 80dB dynamic range of the AGC circuit can meet the design target, and it can easily adjust the output level to ensure the receiver working normally.
