Unsuitable for frequent connection/disconnection.They are less suitable for use in harsh environments than larger connectors. They can operate with frequencies up to 18 GHz. They are smaller and lighter than TNC connectors, making them suitable for applications where size and weight are a concern. Key advantages of SMA connectors include: They are available in several formats, including male vs. Subminiature Version A (SMA) connectors are 50 Ω connectors. Typical applications include mobile telephones and RF antennas. Right-angled versions have a slightly higher level of loss than straight-through connectors, which can be a concern in applications involving frequencies near the operational limit of the connector. They require a specific coaxial cable form. They are heavier and larger than SMA connectors. They are less likely to experience variations in resistance and outer sleeve connection when exposed to mechanical vibrations. They can be used for up to and exceeding 500 cycles. They can operate with frequencies up to 11 GHz. Key advantages of TNC connectors include: However, they are waterproof and more rugged. Threaded Neill-Concelman (TNC) connectors are a miniature threaded variation of BNC connectors. Typical applications include commercial audio/video transmission systems and RF test equipment (e.g., frequency generators, network analyzers, and oscilloscopes). They can experience variations in resistance and outer sleeve connection when exposed to mechanical vibrations. They have a frequency range limited to DC-4 GHz. They lock the connection in place to prevent accidental disconnection caused by vibrations or other movements. They have the simplest design of all coax cable connectors. Key advantages of BNC connectors include: They feature a twist and snap bayonet connection design that requires a quarter-turn to form a connection. BNCīayonet Neill-Concelman (BNC) coaxial cable connectors are one of the most commonly used connector types. Below, we highlight the advantages and disadvantages of several common types of coaxial cable, based on connector, as well as their typical applications. One of the key design elements by which coaxial cables can be categorized is connector type-i.e., the mechanism that connects the cable to other devices. There are many types of coaxial cables available-varying in design and size-to suit different applications. This shielded design enables signal carrying voltage to flow through the central conductor with minimal interference from outside electrical and/or magnetic fields. They generally consist of four layers-the inner conductor layer, the inner conductor insulating layer, the conductive shield layer, and the insulating outer jacket layer. Coaxial cables are a type of transmission cable used to transmit radio frequency (RF) signals.
