RF Connectors are parts used to connect the ends of two shafts to ensure that the centerlines of the two shafts are on the same axis. They are used to connect the master shaft to the slave shaft to transmit the rotational motion of the master shaft to the slave shaft. This article focuses on what types of RF Connectors.

1, SMA RF Connectors. SMA series connector is a widely used small threaded connection of coaxial connectors, life performance and high reliability, widely used in microwave equipment and digital communications equipment RF back to the coaxial cable assembly or microstrip. It is commonly used in wireless equipment on the single board GPS clock interface and base station RF module.

2, SMB RF Connectors. SMB type coaxial connector is a small push-in locking RF coaxial connector, with small size and light weight, easy to use and excellent electrical performance, etc., for radio equipment and electronic equipment in the high-frequency circuit to connect the coaxial cable. In the wireless equipment commonly used in the base station side of the E1 transmission cable to connect the base station DDF small transmission box.

3, BNC RF Connectors. BNC type coaxial connector is a bayonet type RF coaxial connector, with rapid connection and contact reliability, etc., widely used in the field of radio equipment and electronic instruments to connect RF coaxial cable in the wireless commonly used in wireless test instrumentation on the cable connector.

4、TNC RF Connectors. TNC type coaxial connector is a threaded connector type RF coaxial connector, with a wide operating band, reliable connection and good seismic performance, etc., for radio equipment and instruments to connect RF cables, TNC is particularly suitable for mobile communication equipment in the vibration conditions.

5, SMC. SMC type coaxial connector is a small threaded RF coaxial connector, with small size, light weight and good shock resistance and high reliability, for radio equipment and instruments to connect RF coaxial cable.

6、N RF Connectors. N series coaxial connector is a kind of medium and high power connector with threaded connector structure has the characteristics of strong shock resistance, high reliability, excellent mechanical and electrical properties, etc., widely used in vibration and harsh environmental conditions of radio equipment and instruments to connect the RF coaxial cable. Commonly used in GPS antenna and RF module RF connection line, etc.

7, DIN type. DIN type (also called 7/16 or L29) series coaxial connector is a larger threaded connection connector, with strong and stable, low loss and high operating voltage, and most of them have waterproof structure, can be used outdoors as a medium and high energy transmission connector, widely used in microwave transmission and mobile communication system.

On the issue of coaxial connectors, this article focuses on what kinds of coaxial connectors, coaxial connectors are used to transmit RF signals, the transmission frequency range is very wide up to 18 GHz or higher. Different kinds of coaxial connectors have different specific uses, to choose according to the specific purpose.
