What is a coaxial connector, the basic structure, working principle, types, technical parameters, coupling mechanism, application and development status of coaxial connectors 2

2. SMA connector (Submeature version A connector): This is a smaller coaxial connector suitable for applications in the frequency range of DC to 18GHz. It has the characteristics of simple structure and reliable performance, and is commonly used in wireless communication, aerospace and other fields.diode

3. N connector: This is a large coaxial connector suitable for applications in the frequency range of DC to 11GHz. It has high power processing capability and good shielding performance, and is commonly used in fields such as radio equipment and radar systems.diode

4. TNC connector (Threaded Neill Concelman Connector): This is a coaxial connector with a threaded structure, suitable for applications in the frequency range of DC to 11 GHz. It is more suitable for applications in high-frequency and high vibration environments than BNC connectors.diode

5. SMB connector (Submature version B connector): This is a smaller coaxial connector suitable for applications in the frequency range of DC to 4GHz. It is similar to SMA connectors, but smaller in size and is commonly used in fields such as wireless communication and satellite communication.diode

4、 Technical parameters:

1. Frequency range: The frequency range of a coaxial connector refers to the operating range of the connector at different frequencies. The frequency range of different types of coaxial connectors varies, generally ranging from several hundred MHz to several tens of GHz.

2. Impedance characteristics: The impedance characteristics of coaxial connectors refer to the characteristic impedance of the connector, with common impedance characteristics being 50 ohms and 75 ohms. Coaxial connectors with different impedance characteristics have different choices in different applications.diode
