同轴电缆线和测量夹具对滤波器性能的影响

The Influence of Coaxial Cables and Test Fixture on the Performance of Filters

研究了在测量时同轴电缆线和测量夹具对微波滤波器性能的影响。实验结果表明:同轴电缆线的特性阻抗对微波滤波器的通带影响很大,而测量夹具的夹持和固定对整个滤波器的性能也有影响。作者通过实验研究提出了减小该类影响的有效措施。

The influence of coaxial cables and test fixture on the performance of filters was investigated. The experimental results show that, the characteristic impedance of the coaxial cables had a influence on the pass-band performance of filters. The clipping and fixing of the test fixture had a great influence on the entire performance of filters. Last, the effective measures to reduce the influence was put forward.
