摘　　要：提出了一种适用于跳频通信接收机的AGC设计,通过简单的模拟电路实现,并已成功应用于225MHz—512MHz、符号率200k波特/秒、8PSK调制、跳频速率1 000跳/秒的跳频通信接收机。通过对跳频通信接收机的AGC特性进行分析,详细阐述了AGC方案及其电路的实现过程。A design of AGC （automatic gain control） suitable for frequency hopping （FH） communication receiver was presented. The design, which was implemented on simple analog circuit, had been applied FH communication receiver with 225MHz--512MHz, symbol rate 200k Bd/s, 8PSK modulation and FH rate 1 000hop/s. According to the analysis on AGC characteristics of FH corranunication receiver, AGC and its circuit implementation were described in detail.
