FAQ about Coaxial Connectors (RF)
-
1. What is the difference between RF connectors and coaxial connectors?
Structure and performance indicators
There are significant differences between RF connectors and coaxial connectors in structure, application scenarios and performance indicators.
Structural differences
Coaxial connector: Coaxial connector consists of inner conductor, insulation layer, outer conductor and sheath. The inner conductor is used to connect the signal line, and the outer conductor not only serves as the ground wire of the signal line, but also acts as a shield against electromagnetic fields to prevent signal interference.
RF connector: RF connector usually refers to RF coaxial connector, which is similar in structure to coaxial connector, but RF connector focuses more on the transmission of high-frequency signals, so it has higher requirements in material selection and manufacturing process. .
Differences in performance metrics
Characteristic impedance: Characteristic impedance is an important indicator of RF coaxial connectors, which determines the impedance type of the cable connected to it. The characteristic impedance is determined by the inner diameter of the outer conductor, the outer diameter of the inner conductor, and the dielectric constant of the medium between the inner and outer conductors.
Voltage standing wave ratio: The voltage standing wave ratio reflects the matching level of the connector and is an important parameter to measure the performance of the connector.
To sum up, coaxial connector focuses more on general signal transmission, while RF connector focuses on optimized transmission of high-frequency signals. Both have different emphasis on structure, application scenarios and performance indicators.

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.
