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 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. -
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.
