142-0303-406 Classification

Coaxial Connectors (RF)

Coaxial Connectors (RF), the radio frequency coaxial connector, is a professional connector for transmitting radio frequency signals. This type of connector is usually used in radio communications, radar systems, satellite communications, and radio and television. Coaxial connectors are designed with electrical performance and mechanical stability in mind to ensure low loss and high fidelity of RF signals during transmission.

FAQ about Coaxial Connectors (RF)

  • 1. What is coaxial cable in electrical?

    Coaxial cable is a transmission medium consisting of an inner conductor, an insulation layer, an outer conductor and a sheath. The inner conductor is usually one or more copper wires, and the outer conductor is composed of a metal braid or metal foil, both located on the same axis. This structure enables coaxial cables to have lower losses and higher anti-interference capabilities when transmitting high-frequency signals.
    Coaxial cable structure and characteristics
    The structure of coaxial cable includes the following parts:
    Inner conductor: usually consists of a single or multiple copper wires.
    Insulating layer: Located outside the inner conductor, it acts as an isolation and dielectric.
    Outer conductor: usually constructed of metal braid or metal foil to form a shield.
    Jacket: The outer layer that protects a cable, usually made of PVC or Teflon material.

  • 2. What is also called an RF connector?

    RF coaxial connector
    RF connector, also called radio frequency coaxial connector, is a type of radio frequency connector. RF connectors are mainly used for the transmission and connection of radio frequency signals and are widely used in wireless communications, radio, television, radar and other fields.
    historical background
    The earliest RF connector-UHF connector was born in 1930. During World War II, due to war needs, the development of radio, radar and microwave communications promoted the innovation of RF connectors, and series connectors such as BNC, TNC, and N appeared34. After 1958, SMA, SMB, SMC, etc. were miniaturized Products came out one after another. In 1964, the United States formulated the "General Specification for Radio Frequency Coaxial Connectors", which promoted the standardization, serialization and generalization of RF connectors.

  • 3. What is a coaxial plug used for?

    The main uses of coaxial plugs include the following aspects:
    Signal transmission: Coaxial plugs are used to connect both ends of coaxial cables to ensure that electrical signals can be transmitted stably between cables. It provides a stable and reliable connection, ensuring that signals can be transmitted efficiently from one device to another.
    Shielding protection: When connecting to a coaxial cable, the coaxial plug can provide good shielding protection to prevent interference from external interference signals. This can reduce signal attenuation and distortion and improve the quality and reliability of signal transmission.
    Connecting devices: Coaxial plugs can connect different types of devices such as televisions, modems, antennas, etc. It provides a standardized interface that enables various devices to connect and communicate easily.
    Maintenance and replacement: Coaxial plugs are easy to install and replace, making maintenance and replacement of coaxial cables simple and convenient. When a coaxial cable needs to be replaced or repaired, only the connector needs to be replaced rather than the entire cable.
    Application in avionics equipment: Coaxial plugs play an important role in avionics equipment and are used to connect various sensors, controllers, displays, computers and other equipment to achieve signal transmission and electrical connection between equipment. It can provide stable signal transmission and good anti-interference performance to ensure the normal operation of the equipment.
    Application in communication systems‌: In aviation communication systems, coaxial plugs are used to connect antennas and transceivers to realize the transmission and reception of wireless signals. It can provide high-frequency transmission capabilities and good signal quality to ensure stable and reliable communication.
