FAQ about Coaxial Connectors (RF)
-
1. 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. -
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.
