As the demand for intelligent driving systems and in-car entertainment systems in automobiles grows, the in-car signal transmission rate increases, leading to a gradual increase in the transmission frequency of the corresponding connecting cables.

FAKRA coaxial cable is a high-speed high-frequency cable that transmits RF and HD camera signals. Mainly includes the FAKRA connector, FAKRA Inline connector, coaxial cable, and PCB board end connector.

What is RF Cable

RF cable, also called coaxial cable, is a wire and signal transmission line. It consists of a mutually coaxial inner conductor, an outer conductor, and a medium that supports the inner and outer conductors. Coaxial cable is generally composed of four layers of material: the innermost is a conductive copper wire. In contrast, the outside of the wire has a layer of plastic (used as an insulator or medium) around it. Outside the plastic, there is a thin layer of mesh conductor (usually copper or alloy), and then the outermost is a layer of insulating material as the outer skin.

RF cable is an indispensable component of various radio communication

RF connector is a connection device that can reflect and transmit RF signal with a small loss in the RF transmission system and provide fast and repeated connection. Mainly by the contact parts, insulators, shells, and accessories.

RF connector selection conditions should be reliable contact, good conductive insulation performance, sufficient mechanical strength, and plugging and unplugging times to meet the relevant international and domestic standards provisions. At the same time, many factors determine the connector series and style, which is connected to the cable, and the use of frequency range is the main factor.

In engineering practice, make the connector diameter size and cable diameter as similar as possible to minimize reflections. The greater the difference between the cable and connector diameter, the worse the performance. Reflections usually increase as a function of frequency, and generally smaller connectors generally perform well at higher frequency bands.
