摘要
随着电子对抗的日益加剧,捷变频技术在军事通信领域已得到广泛应用。微波捷变频信号发生器作为最基本的测试设备之一,对其关键技术特性功率捷变的要求也越来越高。针对普通ALC环路应用于高速功率捷变的不足,提出了一种高速大动态功率捷变的设计思路,并利用自定义总线技术实现了高速数据传输,时序同步技术确保了数据传输的稳定性,功率校准与补偿方法保证了优良的输出电平准确度,最终实现了ns级功率捷变,并通过仿真和实验进行了验证。
With the increasing of electronic countermeasure,frequency-agile technique has been widely used in the field of military communication.Frequency-agile microwave signal generator is one of the most basic testing equipment,and the key technical characteristics of power agility have increasingly high requirements.Aiming at the deficiency of common ALC loop used for high speed power agility,this paper presents a design idea of high-speed and large dynamic range power agility,and realizes high speed data transmission by using the custom bus technology.The timing synchronization technologies guarantee the stability of data transmission,the calibration and compensation method of power ensure the output level excellent accuracy and achieve ns level power agility finally,which are verified by simulation and experiment.
