Application of 901-128-11

Coaxial Connectors (RF) have become standard components in wireless communications, radio, television, radar, satellite communications and many other fields due to their excellent performance and a wide range of application scenarios. In the field of wireless communication, coaxial connectors are widely used in the connection of base stations, antennas, RF front ends and other equipment to ensure efficient transmission of signals in complex environments. In the field of broadcast television, it is used to connect transmitters, antennas and other equipment to ensure the clarity and stability of the signal. The field of radar and satellite communication is also inseparable from the support of coaxial connectors, which play an important role in high frequency and long distance signal transmission.

901-128-11 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 a coaxial connector?

    Device for connecting coaxial cables
    A coaxial connector is a device used to connect coaxial cables or other electronic devices, primarily used in radio frequency (RF) and microwave communications systems. It effectively reduces signal loss and provides good shielding to prevent electromagnetic interference (EMI).
    Basic structure and working principle
    The basic structure of a coaxial connector includes an inner conductor, an insulator, an outer conductor and a shield. The inner conductor is usually needle-shaped or hole-shaped, the insulator isolates the inner and outer conductors, and the outer conductor and shielding layer provide electromagnetic shielding to prevent signal interference.

  • 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. Are coaxial connectors the same as RCA?

    There are significant differences in appearance and purpose between coaxial connectors and RCA connectors.
    Coaxial connector is a common connector used in electronic equipment and communication systems. It is mainly used to connect coaxial cables to equipment or other circuits. It has good shielding performance and low loss characteristics, and is widely used in wireless communications, television, radio, radar and other fields.
    The RCA connector is an audio interface, usually used for the transmission of analog signals. There are two types of RCA interfaces: one is the RCA coaxial interface, which looks the same as the analog RCA interface, and the other is the BNC coaxial interface, which looks similar to the common signal interface on a TV and has a locking design. The impedance of RCA coaxial cable is 75 ohms. Although the appearance is the same as the analog RCA interface, mixed use will cause unstable sound transmission and affect the sound quality.
    Coaxial connectors and RCA connectors also differ in application scenarios and transmission characteristics.
    Coaxial cables are suitable for high-frequency signal transmission, such as television, Internet, and wireless communications, while RCA cables are suitable for low-frequency signal transmission, such as audio and standard-definition video‌3. In addition, the coaxial transmission impedance is constant and the transmission bandwidth is high, which can ensure the quality of the audio. However, the impedance of the RCA coaxial cable is also 75 ohms, and mixed use will lead to a decrease in sound quality.
