| 摘 要： | 针对传统自动电平控制（ALC）在跳频发射机控制过程中存在功率过冲、建立时间长的技术弊端，提出了一种改进的ALC电路的实现方法,即跳频时钟禁发法。工程实践证明，所提方法是解决该瓶颈的有效方法，已成功应用于某跳频通信电台中。

| Abstract: | There exist technical limitations in traditional Automatic Level Control (ALC) method, such as power overshoot and longer establishment time.In this paper,an improved ALC circuit using Frequency Hopping (FH) time clock to prohibit power transmission is proposed. The engineering practice has proven that the improved ALC circuit can effectively overcome the above-mentioned limitations and it has been successfully applied in a FH radio. |

| Keywords: | FH communication automatic level control power overshoot and zeroization PA gain transimission prohibition method |
