SAE USCAR 18-4:2016

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.
