SAE USCAR17-7

This document contains procedures for testing performance of SMB-style electrical terminals, connectors, and components for coaxial cable connection systems intended for road vehicle applications. These are often called FAKRA II designs. This specification does not apply to the Non-RF portion of a Hybrid RF connection system. The intent of this specification is to qualify sealed and unsealed RF connectors that operate at frequencies from DC to 6 GHz. The characteristic impedance of the SMB/FAKRA connection system is 50 ohms however this specification does not exclude the use of these RF connectors on non-50-ohm cables or systems. This specification does not apply to single conductor wire or twisted pair connection systems. This specification (along with SAE/USCAR-18) is designed to provide the mechanical and electrical data required to ensure that assemblies from various manufacturers will perform reliably in actual conditions. There is intermateability testing included in this specification. End users who may be concerned about intermateability are responsible to request the supplier complete this testing.
