摘　　要：提出了一种低驻波的微带均衡器结构,并对该结构进行了理论分析、设计、制作和测试。该结构通过在微带线相隔四分之一波长处放置了2个加载了电阻的微带支节构造而成。测试结果显示,设计衰减量为3dB,工作频带为3.2GHz～3.4GHz的微带均衡器的最小衰减量小于0.4dB,最大衰减量为2.9dB,驻波在整个工作频带内低于1.18,测试结果与设计值符合较好。A structure of microstrip equalizer with low VSWR is proposed. The theory, design, fabrication and its measurements are presented. This equalizer is composed of two microstrip branches with resistors which are at a distance of 1/4 wavelength. Experimental results show that the minimum attenuation is less than 0.4 dB, the maximum attenuation is 2.9 dB and the VSWR is below 1.18 with designed 3 dB attenuation at the frequency range from 3.2 GHz to 3.4 GHz. The experimental results is correspond well with the theory.
