Design and experiment of microwave pulse compressor with adjustable coupling coefficient

  • 摘要: 针对有源能量倍增器法(SLED)脉冲压缩实验中对储存能量阶段和释放能量阶段耦合度调节的需求,利用支臂短路波导H-T的调配功能,设计了一种耦合度可调节的SLED脉冲压缩装置。基于散射矩阵理论,分析了支臂短路波导H-T对SLED脉冲压缩装置耦合度的调节能力。利用大功率波导环形器代替3 dB耦合器,进行了基于单储能腔的无源SLED脉冲压缩实验,实验结果表明,支臂短路波导H-T对耦合度的调节能力与理论分析相吻合。
