众所周知,双锥取样器是一种超宽频带取样器件,但由于取样二极管的装入,使双锥取样器的传输和取样特性大为变坏,为了消除取样二极管的这一不利影响,在取样器的中心安装了补偿器,补偿器的阻抗匹配作用,是实现取样器的超宽频带性能的关键之一,本文在理论分析的基础上,提出了补偿器的工程设计公式,实验表明,理论与测试结果相符合。
It is well-known that the double-cone sampler is an ultra-wideband sampling device. However, due to the loading of the sampling diode, the transmission and sampling characteristics of the double-cone sampler are greatly deteriorated. In order to eliminate the adverse effect of the sampling diode, In the center of the device, the compensator and the impedance matching function of compensator are one of the keys to realize the ultra wideband performance of the sampler. Based on the theoretical analysis, this paper presents the engineering design formula of the compensator. Experiments show that the theory In line with the test results.
