【摘要】 本文设计出一个匹配良好的Ka波段微带线增益均衡器,驻波比在带内小于1.5。选择薄膜电阻加载的枝节谐振单元作为构成陷波器响应的基本结构。通过大量的仿真和分析,研究了谐振单元中枝节的位置、宽度和长度及薄膜电阻的长度和阻值等参量对衰减曲线的影响。利用三个加载了不同阻值的枝节谐振单元得到了一个Ka波段微带线增益均衡器,给出了结构图及衰减曲线S21和驻波比ρ的曲线。结果表明这种加载薄膜电阻的谐振单元适合Ka波段微带线增益均衡器的设计。更多还原

【Abstract】 A good matched Ka-band Microstrip equalizer is designed in the paper.The VSWR is less than 1.5 in the whole Ka-band.The thin-film resistor loaded branch resonator is chosen as the essential structure of subsidence filter response.The impact of location,width and length of branch resonator.The length and value of thin-film resistor for attenuation curve is researched through numerical simulations and analyses.Three branch resonators with different values of thin-film resistor are used to realize a Ka-band equalizer.The construction,frequency performance curve and VSWR curve are also given.The results show that this method of using thin-film resistor loaded branch resonator is quite suitable for the design of Ka-band microstrip equalizer.更多还原
