摘　　要：提出一种具有自动增益控制(AGC)的WCDMA选频式直放站的上行链路系统。基于系统功能电路图,详细地分析了该系统的模拟AGC的电路控制算法,并利用电路设计软件Advanced Design System(ADS)进行了系统级模拟。仿真结果表明此系统具有通带增益大、邻道抑制比高和输出功率稳定可调的优点,适用于WCDMA移动通信系统。This paper introduces the uplink system with automatic gain control for WCDMA frequency selective repeater. Based on the system function diagram, the algorithm of analog automatic gain control are analyzed. The results of ADS simulations show that the proposed system is performed well, which has the characteristic of large pass band gain, high adjacent channel power ratio （ACPR） and steady controllable output, and that it can be used for WCDMA.
