Coaxial cables are a type of transmission cable used to transmit radio frequency (RF) signals. They generally consist of four layers鈥攖he inner conductor layer, the inner conductor insulating layer, the conductive shield layer, and the insulating outer jacket layer. This shielded design enables signal carrying voltage to flow through the central conductor with minimal interference from outside electrical and/or magnetic fields.聽 There are many types of coaxial cables available鈥攙arying in design and size鈥攖o suit different applications. One of the key design elements by which coaxial cables can be categorized is connector type鈥攊.e., the mechanism that connects the cable to other devices. Below, we highlight the advantages and disadvantages of several common types of coaxial cable, based on connector, as well as their typical applications.聽 BNC聽
Key advantages of BNC connectors include:聽 Simple design. They have the simplest design of all coax cable connectors.聽 Easy connection. They do not require any tools. Small accidental disconnection risk. They lock the connection in place to prevent accidental disconnection caused by vibrations or other movements.聽Some of the disadvantages include:聽 Limited frequency range. They have a frequency range limited to DC-4 GHz. High susceptibility to variations. They can experience variations in resistance and outer sleeve connection when exposed to mechanical vibrations.聽Typical applications include commercial audio/video transmission systems and RF test equipment (e.g., frequency generators, network analyzers, and oscilloscopes). TNC
Key advantages of TNC connectors include:聽 High frequency capacities. They can operate with frequencies up to 11 GHz. High mating cycle life. They can be used for up to and exceeding 500 cycles. Low susceptibility to variations. They are less likely to experience variations in resistance and outer sleeve connection when exposed to mechanical vibrations.Some of the disadvantages include:聽 Large size, heavy weight. They are heavier and larger than SMA connectors.聽 Specific attachment requirements. They require a specific coaxial cable form. Potential for higher loss. 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.聽Typical applications include mobile telephones and RF antennas.聽 SMA
Key advantages of SMA connectors include:聽 Small size, light weight. They are smaller and lighter than TNC connectors, making them suitable for applications where size and weight are a concern. High frequency capacities. They can operate with frequencies up to 18 GHz.Some of the disadvantages include:聽 Less robustness. They are less suitable for use in harsh environments than larger connectors. Unsuitable for frequent connection/disconnection. They are not designed for applications that require frequent connection and disconnection.Typical applications include microwave systems, telecommunications equipment, and Wi-Fi antennas. 7/16 DIN
Key advantages of 7/16 DIN connectors include:聽 High intermodulation rejection. They offer higher intermodulation rejection than BNC or N connectors. High power capacities. They handle higher power levels than most other connectors.聽Some of the disadvantages include:聽 Harder connection/disconnection requirements. They need a wrench for connection and disconnection. Incongruous with US standards. They are generally used in Europe rather than the United States.聽Typical applications are base stations, broadcast communication systems, and other situations involving multiple transmissions.聽 QMA
Other key advantages of QMA connectors include:聽 High power capacities. They can handle higher power levels than some of the other connector types. High frequency capacities. They can operate with frequencies up to 18 GHz.Their primary disadvantage is the lack of waterproofing. They are not suitable for use in environments where exposure to moisture is expected. However, they are ideal for use in industrial and communications applications that require the maintenance of the shielding barrier. MCX
Key advantages of MCX connectors include: Similar to SMB connectors but are 30% smaller. Easy installation. They have a snap-on coupling design that makes installation simple and quick.Some of the disadvantages include:聽 Limited frequency range. They have a frequency range limited to DC-6 GHz. Variable sizes. They can vary in size depending on the manufacturer.Typical applications include digital cellular systems, global positioning systems (GPS) devices, RF hardware, and TV tuner cards. RCA聽
Key advantages of RCA connectors include:聽 Wide availability. They are readily available. 聽 Low cost. They are relatively inexpensive.聽The main disadvantage is the color code system. It can be difficult for some users to navigate, especially in more complex systems.聽 Typical applications include audio and video systems, such as camcorders, digital cameras, stereo systems, and televisions.聽聽 Partner With Electro-Prep for Your Coaxial Cable Needs!Looking for a coaxial cable for your RF application?
