Introduction

At present, under the new development trend of electrification, intelligence and networking of vehicles, more and more communication interconnection and infotainment equipment are being installed.

When used in automobiles, these devices have higher requirements for signal and data transmission performance. Therefore, the 50 ohm impedance radio frequency The relevant standards for the frequency connection system interface will help promote the standardized development of related industries and facilitate domestic and international technical exchanges and trade. Easy to work with.

GB/T 44644 "Road Vehicle 50 ohm Impedance Radio Frequency Connection System Interface" is intended to consist of two parts.

--- Part 1: Dimensional and electrical requirements. The purpose is to specify the male terminal connection of the 50 ohm impedance RF connection system interface of road vehicles The dimensions and electrical characteristics of the transducer and female connector are as follows.

--- Part 2: Test methods. The purpose is to specify the male and female connectors of the 50 ohm impedance radio frequency connection system interface of road vehicles Test methods for terminal connectors.

1 Scope
