What are the main types of RF connectors?

Published On: May 22nd, 2023Categories: Fundamentals

RF connectors, also known as radio frequency connectors, are types of electrical connectors designed to connect and transmit radio frequency signals between devices. They are widely used in various applications, including telecommunications, broadcast, aerospace, military, and consumer electronics.

Here are some common types of RF connectors:

  1. BNC (Bayonet Neill-Concelman): BNC connectors are quick-connect connectors that use a bayonet-style coupling mechanism. They are commonly used in video and RF applications, such as CCTV cameras and Ethernet networks.
  2. SMA (SubMiniature version A): SMA connectors are widely used in high-frequency applications. They have a screw-type coupling mechanism and are commonly used for connecting antennas, RF cables, and wireless devices.
  3. N-Type: N-Type connectors are designed for applications that require low signal loss at high frequencies. They feature a threaded coupling mechanism and are commonly used in telecommunications, broadcast, and test equipment.
  4. TNC (Threaded Neill-Concelman): TNC connectors are similar to BNC connectors but feature a threaded coupling mechanism. They are commonly used in applications that require a reliable connection, such as Wi-Fi antennas and radio communications.
  5. SMB (SubMiniature version B): SMB connectors are smaller versions of SMA connectors and use a snap-on coupling mechanism. They are commonly used in applications where space is limited, such as GPS systems and satellite communications.
  6. MCX (Micro Coaxial): MCX connectors are even smaller than SMB connectors and feature a snap-on coupling mechanism. They are commonly used in compact devices like portable radios, mobile phones, and GPS receivers.
  7. MMCX (Micro Miniature Coaxial): MMCX connectors are even smaller than MCX connectors and also use a snap-on coupling mechanism. They are commonly used in small-scale applications like Bluetooth devices, wireless routers, and GPS modules.
  8. F-Type: F-Type connectors are primarily used in cable television (CATV) and satellite TV systems. They have a threaded coupling mechanism and are commonly used to connect coaxial cables to devices like TVs, set-top boxes, and satellite receivers.

These are just a few examples of the many RF connectors available in the market. The choice of connector depends on factors such as the frequency range, power handling capacity, size, and specific application requirements.
