RF cable is a type of cable used to transmit electromagnetic energy. It is an essential component of various radio communication systems and electronic devices, including wireless communications, radar, television, and navigation. Besides, RF cables are widely used in instrumentation and computers. However, some considerations need to be taken while choosing the proper cable for a particular application. 

This kind of cable is designed to reduce the risk of interference from other sources. Unlike coaxial cables, RF cables have four-circular layers, one for each wire carrying the signal, one for each channel, and a metal shield at the end of the cable. All four layers protect the signal from outside interference. The insulating material encloses a metal shield and is protected by a plastic casing.

RF coaxial cable is an ideal choice for high-frequency communications. This cable is made from an insulating spacer, a solid high-frequency dielectric, and an insulating layer. The insulating spacer protects the signal from unwanted signals and RFI/EMI interference. Air-insulated coaxial cables are also commonly used in military/aerospace applications and telemetry.

Specification of RF Cables

RF cables are often characterized by the outer conductor, which is typically copper braid. This allows for a flexible coax cable. Certain types of RF cables have a solid outer conductor, which means that the outer layer is made up of copper. Triple-screened coax cables are constructed by placing one braid over another. In some cases, an outer layer is made from copper foil or tape, which reduces stray pick-up and radiation.

RF cable can be referred to as coaxial cable and is used to transmit signals up to several gigahertz. Since it has both a transmitter and a receiver, it is often used in high-frequency environments and is impervious to external EMI. It is also helpful for protecting weak signals that are susceptible to interference. A coaxial cable, on the other hand, is impenetrable by EMI.

Benefits of RF Cables

The main benefits of using coaxial cables are the tight impedance and RFI/EMI control, which is crucial for microwave and 50 ohm RF applications. However, signal loss can be harmful to overall system performance and should be avoided.

In many cases, RF cable is made of copper braid outer conductors. This makes it flexible and durable. Solid copper braid outers are used in some varieties but are rare in most cases. Double-screened and triple-screened coax cables are also available. The additional layers of screening reduce the amount of stray radiation and pick-up signals. These types of cables are ideal for applications involving a high-frequency signal, such as televisions and radios.

The most common type of RF cable is called the RG type. RG-6 is a typical example of a home video cable. An RF connector carries RF signals from the router to the antenna. It’s possible to use different kinds of RF cables for various applications. Whether you need a high-frequency or low-frequency signal, you can find them in the right size and form.
