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. 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.


  • 3. What is a coaxial F-type connector?

    Coaxial RF connector, F-type connector
    The coaxial F-type connector is a radio frequency coaxial connector, which is widely used in the fields of cable TV, satellite TV, cable TV modem and TV connection. It is characterized by threaded connection, convenient insertion, and stable performance. It is suitable for occasions with impedance matching requirements and non-matching occasions.
    Definition and historical background
    The F-type connector was first invented by Eric Winston in the early 1950s and became a common connection connector for VHF television antennas in the United States in the 1970s. Its characteristic impedance is 75 ohms, and the highest frequency can generally support 1GHz or 2.4GHz.
