Optimization of VSWR in Connection of Bundled RF Cable Assembly

为解决集束型射频同轴电缆组件转接设计时电压驻波比(VSWR)大、电缆组件传输性能低等问题,提出了集束型射频同轴电缆组件转接VSWR的优化方法。该方法通过对电缆组件特性阻抗进行轴向错位距离补偿,完成各连接之间特性阻抗的一致匹配,从而降低VSWR。仿真结果表明,该方法使得各电缆组件连接之间阻抗匹配一致,解决了电缆组件转接设计时的特性阻抗失配问题,能够有效降低VSWR,提高电缆组件的传输性能。

In order to solve the problems of high voltage VSWR and low transmission performance of bundled RF coaxial cable assembly switching design,an optimized method for bundled RF coaxial cable assembly switching VSWR is proposed.This method compensates the axial misalignment distance of the characteristic impedance of the cable assembly to achieve a consistent matching of the characteristic impedances between the connections,thereby reducing the VSWR.The simulation results show that this method makes the impedance of each cable assembly connection consistent,and solves the problem of mismatch of characteristic impedance when the cable assembly is switched over,which can effectively reduce the VSWR and improve the transmission performance of the cable assembly.
