电连接结构的信号完整性分析

With thedevelopment trend of high-speed connector faster and smaller, the signal integrity of connector is becoming more serious. The problem of signal integrity has become a hot issue and an urgent problemin the current high-speed system research. In this paper, a pair of differential pairs of Type-c electrical connectors are used to study the characteristic impedance, insertion loss , return loss of different structures to Type-c electrical connectors from two aspects: insertion depth and dielectric constant of dielectric layer by using HFSS simulation software.The paper concludes that the connector structure with smaller insertion depth has the better transmission performance. When the dielectric constant of the dielectric layer is 3.8, the transmission performance of the connector is the best.
