Abstract

Periodic impedance caused by periodic structure in transmission lines is simulated by high frequency 3-D EM simulators and RF/MMW circuit simulator. From the simulated data, the dip trend of insertion loss, which is also called as suck-out effect of high speed bulk cable, is presented. A simplified N-section LC lumped-circuit model with periodic circuit elements interpreting the periodic structure of transmission line is proposed for describing the dip trend, suck-out effect, of insertion loss. With proper number of sections, under the condition of quasi-static, the lumped circuit model could also perform the suck-out effect due to the periodic structure up to several tens GHz frequency range.
高速输电线路周期性缺陷结构造成的高倾斜插入损耗
利用高频三维电磁模拟器和射频/毫米波电路模拟器对传输线中周期结构引起的周期阻抗进行了仿真。根据模拟数据,给出了插入损耗的下降趋势,即高速散装电缆的吸出效应。为了描述插入损耗的倾斜趋势和吸出效应,提出了一种简化的n段LC集总电路模型,该模型具有解释输电线周期结构的周期电路元件。在准静态条件下,当截面数适当时,集总电路模型由于其周期结构在几十GHz频率范围内也能发挥吸出效应。
