Coaxial connectors are electronic components used to connect coaxial cables and equipment, providing low loss signal transmission and high frequency bandwidth. Coaxial connectors consist of internal and external conductors that transmit signals between input/output devices.
A coaxial connector is an electronic component that connects coaxial cables to equipment. They are usually circular, have external threads, and use central leads for signal transmission. This type of connector is widely used in base stations, satellite communication, radar, testing and measurement, and other fields that require high-speed data transmission.
There are various types of coaxial cable connector, including BNC, TNC, SMA, N series, and so on. BNC connectors are the most common type, with a relatively simple structure that can support frequencies up to 4GHz. SMA connectors are more commonly used in high-frequency applications, such as millimeter wave radar and satellite communication. In addition, there are many other types and sizes of coaxial connectors that can be selected and used according to different needs.

Types of Coaxial Connectors
Coaxial cable connectors are used to connect cables to other devices and are specifically designed to maintain the shielding on the cable. High-quality connectors offer reliable, long-lasting connections.
BNC
The Bayonet Neil-Concelman (BNC) coaxial connector is aminiature-to-subminiature RF connector used for quick connect/disconnect in RF equipment, test instruments, radio, television, and video signal.
TNC
TNC Connectors are weatherproof, miniature units that operate up to 12 GHz and are commonly used in cellular phone and RF/antenna connections to resolve leakage and stability issues.
SMB
Subminiature version B connectors are smaller versions of SMA connectors, and provide superior electrical performance from DC to 4 GHz. SMB connectors offer a simple snap-on coupling design for semi-rigid cables with infrequent connections.
SMA Type Connector
SMA type connector is a small coaxial cable connector suitable for high-frequency and low-power digital and analog signal transmission, widely used in wireless communication, radar, microwave equipment, satellite communication and other fields. Its characteristics are convenient connection, small size, and low insertion loss in the circuit, making it suitable for situations that require high frequency range and high-precision transmission.
SMA type connectors are composed of outer sleeves, center pins, insulators, and other parts, which are connected through plug-in connections. Its characteristics are small size, low insertion loss, wide applicable frequency range, and good anti-interference performance. However, it has fewer insertion and removal times, and its application scenarios are relatively limited.
7/16 DIN
The 7/16 DIN (Deutsches Institut fir Normung) connector is a threaded RF connector for high-wattage transmissions in cellular networks, antenna systems with multiple transmitters, and defense applications.
QMA
QMA connectors are the quick-lock and quick-disconnect variation of SMA connectors and feature the same internal construction.
MCX
Featuring a 30% smaller outer diameter than SMB connectors, MCX connectors operate between DC and 6 GHz in wireless, GPS, TV tuner cards, RF hardware, and digital cellular applications.
N-type Connector
N-type connector is a commonly used large coaxial connector, suitable for analog and digital signal transmission with a wide frequency range, and widely used in radar, wireless communication, microwave equipment and other fields. Its characteristics are wide frequency range, good electromagnetic interference resistance, reliable connection, but large volume.
The N-type connector consists of an outer sleeve, a center pin, an insulator, a threaded sleeve, and other parts, which are connected by rotation. Its characteristics are a wide frequency range, good anti jitter performance, suitable for high-power radio equipment, but it has a large insertion and extraction force, making it inconvenient to move.
Why Choose FBelec Ultra-fine Coaxial Cable Connector?
The ultra-fine coaxial cable connector is specifically designed to process high-frequency signals with minimal loss. Unlike traditional cable connectors, ultra-fine coaxial cables have less attenuation and can achieve effective signal transmission over long distances. For example, in wireless communication systems, ultra-fine coaxial cable connectors can maintain the strength and clarity of the signal between the antenna and mobile devices, ensuring a robust and reliable connection.
The precise structure and high-quality materials of ultra-fine coaxial cable connectors can significantly improve the integrity of signals. These connectors can minimize electromagnetic interference (EMI), crosstalk, and signal reflection to achieve cleaner and more accurate signal transmission. For example, in medical imaging systems such as MRI scanners, micro coaxial cable connectors help transmit high-resolution images without distortion caused by signal attenuation.
The ultra-fine coaxial cable connector is also suitable for application in devices with limited space due to its compact construction. They are compact in appearance and can be effectively integrated into electronic devices without affecting performance. For example, in automotive radar systems, micro coaxial cable connectors can connect the radar module and antenna, ensuring precise and reliable object detection with a compact and streamlined design.
The ultra-fine coaxial cable connector has excellent high-frequency capability and can transmit signals in the gigahertz (GHz) range. This makes them suitable for various applications that require fast data transmission rates, such as high-speed data communication and video transmission. In the aerospace industry, ultra-fine coaxial cable connectors are used in satellite communication systems to transmit high-frequency signals over long distances with minimal signal loss.
Ultra fine coaxial cable connectors have become the preferred choice for high-frequency signal transmission due to their ability to minimize signal loss, improve signal integrity, compact size, high frequency capability, and enhanced shielding capability. Their performance is evident in various industries, including wireless communication, medical imaging, automotive radar, aerospace, and industrial automation applications.
FAQs
Precautions during using Coaxial Connector?
1. Incorrect connector model used
The dimensions of coaxial RF connectors include 2.4 mm, 2.92 mm, 3.5 mm, etc. Mixing different sizes may not only cause loose connections but also permanent mechanical damage to the interface.
2. A faulty connector was used.
Defective connectors need to be discarded in a timely manner, otherwise it will affect other devices connected to them. For example, a male connector with a skewed pin may damage the inner conductor of the female connector connected to it.
3. Using the wrong torque wrench to tighten the connector
The use of a torque wrench is to ensure that the force applied to each connection is the same, that is, it is tightened equally every time, which can achieve a repeatable connection effect and ensure that the connection head is not damaged due to excessive force. Different connectors require different torque wrenches due to their different sizes, materials, and properties. At the same time, the position and angle that the torque wrench grasps need to strictly follow the instructions and operate in a standardized manner.
