一种SMA型射频连接器及电缆组件的设计与实现

文中提出了一种配接SMA型射频同轴连接器的电缆组件。通过共面补偿优化设计以及对装配过程中影响电缆组件电性能指标的关键因素进行分析，设计了SMA型射频连接器，并配接射频电缆加工了电缆组件。在整个工作频段（0.01～18）GHz，测试的电缆组件电压驻波比VSWR_电缆组件<1.12，通过计算，单个连接器电压驻波比VSWR_连接器<1.06。所提出的配接SMA型射频连接器电缆组件的电压驻波比性能较常见的同类电缆组件有明显改进。电缆组件的测试结果与仿真结果具有较好的一致性，验证了设计的有效性。

Design and Realization of a Cable Assembly with SMA-style RF Connector

This paper presents a novel cable assembly with SMA-type RF （ radio frequency） coaxial connector. By adopting the method of coplanar-offset and analyzing the important aspects of affecting the performance of the whole cable assembly, SMA-style RF connector is designed and fabricated to make the cable assembly. During the whole frequency band （0. 01~18） GHz, the measured VSWR of the whole cable assembly is less than 1 . 12 . The calculated VSWR of the designed connector is less than 1 . 06 . The VSWR performance of the proposed cable assembly with SMA-type RF connector is better than the VSWR of this kind of familiar cable assembly. The simulated and measured results of the proposed cable assem-bly are in good agreement to validate the design.
