摘要
主要介绍了一种适用于225—512MHz的宽带数字中频AGC接收机的设计,该接收机的信号带宽是5MHz,OFDM调制。通过对宽带信号接收机的需求进行分析,详细阐述了AGC电路及控制方案的逐步实现过程。
A digital broadband intermediate frequency （IF） AGC receiver applying to 225-512MHz is mainly introduced. The signal bandwidth of this receiver is 5MHz with OFDM modulation. By analyzing the requirements of the broadband signal receiver, the AGC circuit and the progressive realization of control method are illustrated in detail.
