RF Connectors: Radio Frequency Coaxial Cable Connectors

Image
There’s a wide range of RF connectors in use with coaxial cable to provide screened connections. These coaxial cable connectors find applications in several areas. They are preferred to carry radio frequency (RF) signals and to provider higher levels of screening that are otherwise not possible with the use of more ordinary connectors or open connectors. RF connectors are used in a large number of areas. Primarily, their uses are associated with RF applications usually with coaxial cables. So, RF connectors can be seen from commercial and professional applications as well as domestic television, ham radio, and CB.   Coaxial connectors with RF connectors are also commonly seen in areas where screening is the top priority rather the fundamental RF properties. In these areas, coaxial connectors are used with different types of test equipments. A common application of RF connectors is their use on oscilloscopes. Obviously, there are several other applications of RF connectors. B...

Common types of coaxial cable

Image
As we know that, the coaxial cable is popularly used to transmit electrical signals from one electronic system or component to another. They are considered as one of the most durable cable types. Coax cable mainly consists of four different layers that is center conductor usually made of copper, surrounded by plastic dielectric insulator, then copper braided layer, and at last plastic covering to prevent internal damage. Coax cables are of different types and major three of them are discussed below-   Flexible coaxial cable Flexible coax cable is the most common type of coax cable which is mainly used for its excellent flexibility. It is also known as braided coaxial cable because it has braided outer layer of fine conducting wires that act as a shield to the center conductor. If required, the shielding capability of these braided layers can be increased by adding extra layer of aluminum fold over the braid. Being flexible, they are widely used for military and aerospace applic...

Discussing Different types of RF connectors

Image
RF connectors are widely used in a number of industries to establish electrical connection for seamless signal transmission in radio frequency applications. Applications that require frequency transmission in range 0 to 18 GHz and above use RF connectors. While there are several types of RF connectors , in general, they all have one male connector and one female connector. Male connectors are known as plug and females as jack. The connectors feature a center pin and an outer grounding with a locking mechanism to ensure a strong and reliable connection.  Selection of the best RF connector for an application depends on the frequency range, size, performance, and shape of the connector. Let’s talk about the commonly used RF connectors: SMA One of the most widely used RF connectors, SMA connectors are smaller in size and offers reliable performance. It is known as the best connector when it comes to impedance matching. The commonly used ones are 3.5 mm connectors. They are used...
