摘要
研究了用于均衡行波管增益的微波均衡器的计算机仿真和工程设计问题。理论分析并建立了均衡器的一般微波网络模型,该网络模型具有数十个优化变量,能够使均衡器实现任意有理函数类的均衡曲线。利用遗传优化算法完成多变量的单目标或多目标优化,最终根据优化结果来具体实现均衡器的工程设计并为后期调试提供指导。设计了一种C波段10阶同轴均衡器,实物调节和测试表明该设计对该波段的各种均衡曲线均有很好的适应性,均衡误差1d B以内,其中均衡枝节还具有温度补偿特性,高低温温飘小于5MHz。
This paper presents the optimization algorithm and the engineering designing method of the equalizer for the TWT amplifier. In order to be able to approximate any reasonable equalization curve,a precise analytical microwave network modal is constructed with a bunch of parameters that need to be optimized and the genetic algorithm is introduced here to approach the best solution which will realize the design of the equalizer and give the direction of post tuning. A 10 order equalizer is optimized,designed and tested,with the simulation result showing the designing approach is quite adaptive to many kinds of equalization curve,and the test report of the deivce verifies the effectiveness of the algorithm.
