本文件是对SAE/USCAR 17的补充，旨在给出单向和双向射频连接器的推荐用途，以及目前其他地方未规定的双向射频连接器和混合（射频和直流电源）连接器的尺寸要求。本文规定的射频（RF）连接器接口适用于不密封和密封的高达6 GHz的汽车应用，并适用于在线、板安装、设备安装、直线或角度应用。本文件规定了尺寸要求，以确保互换性。符合本规范的尺寸要求不能保证不同供应商之间的互操作性。供应商有责任确保与其他供应商匹配的连接器满足射频性能要求。SAE/USCA中规定了性能要求- 2和SAE/USCAR-17。

This document is a supplement to SAE/USCAR 17 and is intended to give recommended usages for one and two-way RF connectors and dimensional requirements for 2-way RF connectors and hybrid (RF & DC power) connectors which are not currently specified elsewhere. The radio frequency (RF) connector interface specified herein is suited for unsealed and sealed automobile applications up to 6 GHz and is intended for in-line, board mount, device mount, straight or angled applications. Dimensional requirements are specified in this document to ensure interchangeability. Compliance with the dimensional requirements of this specification will not guarantee interoperability between different suppliers mating connectors. It is the supplier responsibility to ensure RF performance requirements are met with other suppliers mating connectors. Performance requirements are specified in SAE/USCAR-2, and in SAE/USCAR-17.
