Coaxial Cable Connector Types

Posted on December 29, 2020 David Atkinson Aviation

A coaxial cable connector is a type of connector used to connect cables to other devices while maintaining the cable shielding. These connectors offer reliable, long-lasting connections. Connectors feature a plug, also known as the male component, and socket, known as the female component. Depending on the size and frequency of the connector, some may be genderless and mounted flush instead of mating.Throughout the digital, video, audio, RF, and microwave industries, there are many coaxial cable connector types, each offering unique benefits based on their end use or application. This blog will discuss the most common types of coaxial connectors as well as their unique characteristics and intended applications.

BNC, or Bayonet Neil-Concelman coaxial connectors are miniature-to-subminiature RF connectors used for rapid connect and disconnect in RF equipment, test instruments, radio, television, and video signals. BNC connectors feature two bayonet lugs for a twisting interface on the female connector and are best at frequencies below 4GHz. Connectors of this type were originally designed for military use.
The Threaded Neil-Concelman (TNC) is a threaded version of a BNC connector that performs better in microwave frequencies than BNC connectors. They are weatherproof, miniature units that operate up to 12 GHz. Their most common uses are in cell phone and RF/antenna frequencies where they resolve leakage and stability issues.
Subminiature Version B (SMB) connectors are smaller versions of SMA connectors and provide superior electrical performance from DC to 4GHz. These are among the most popular connector variations for industrial and telecommunications applications. SMB connectors offer a simple snap-on coupling design for semi-rigid cables with infrequent connections.
7/16 DIN
This connector is a threaded RF connector for high-wattage transmissions within cellular networks, antenna systems with multiple transmitters, and defense applications. These connectors can be used at up to 7.5 GHz and require a wrench for proper tightening and installation. The name 7/16 refers to the 7-mm inner diameter of the female inner contact and the 16-mm inner diameter of the outer contact.
QMA connectors are the quick-lock and quick-disconnect variation of SMA connectors and feature the same internal construction. Connectors of this type are ideal for industrial and communications applications, as well as cable wiring, assembly, and repair, where they offer faster and safer coupling.
MCX, or micro coaxial connectors are small-form-factor connectors ideal for applications with space, size, or weight restrictions. MCX connectors offer a 30% smaller diameter than SMB connectors and operate between DC and 6 GHz in wireless, GPS, TV tuner cards, RF hardware, and digital cellular applications. They also provide simple installation without the need for tools thanks to their snap-on coupling design.
The RCA (Radio Corporation of America) connector, also known as a cinch connector, was originally designed to transmit audio signals but is now commonly used in video as well. RCA connectors are sometimes called A/V jacks and are easily recognizable as the red, white, and yellow cords that plug into the back of televisions. Each of these cables comprises a male connector surrounded by a ring.
