摘要
设计了一种用于3.7GHz低杂波电流驱动(LHCD)系统的高功率3db功分器。论文基于奇偶模理论和S参数矩阵分析,得到初步的3db功分器结构参数,然后利用高频仿真软件HFSS进行结构仿真和参数优化,得到最优结构,使得3db功分器的VSWR=1.02、D=35db、C=3.03db、I=38.2db。同时详细分析了大功率下的热损耗情况,提出了合理的散热方式,保证了功分器在长脉冲大功率时,表面平均温度处于63℃的平衡状态。
This paper deals with the design of high power 3db power splitter used in 3.7GHz Lower Hy- brid Current Drive (LHCD) system , The initial structure parameters are obtained by analyzing the theory of o-model and e-model and S parameters matrix. Further analysis is performed by High Frequency Structure Simulator (HFSS) program whieh make sure C=3.03 db, D=35db, I=38,2db. The thermal generation and cooling means for the large power transmission situation is analyzed too and the final average temperature is 63℃.
