宽带双圆锥取样器的研制

The Study and Manufacture of the wide-band Biconical Sampler

本文对双圆锥型取样器进行了理论分析,提出了这种取样器的设计方法和全套计算公式,并据此进行了实际的工程设计。经过加工、安装、实验调整和测试,该取样器的带宽为0～12.4GHz;带宽内灵敏度平坦,小于3dB;驻波系数小于2.2.说明本文提出的理论分析,设计方法和计算公式是正确的,制做的取样器的性能是优良的。

The theoretical analysis and a complete set of formulas for designingbiconical sampler are given in this paper. On the basis of these formulasand principles, a biconical sampler has been successfully designed, assembledand tested. That bandwidth of this sampler is from O to 12.4GHz. Thesampling sensitivity is flat within its bandwidth, with a slight decreaseof less than 3dB at the upper frequency end. The standing wave ratiois less than 2.2 over the bandwidth. The experimental data show thatthis sampler possesses a good performance.
