Types of RF Coaxial Connector
Subminiature version A
SMA connectors are a common type of RF connector, especially for high-frequency RF applications. It adopts threaded connection, has good mechanical and electrical properties, and is widely used in microwave communication and testing instruments.
Bayonet neill-concelman
BNC connectors are known for their unique rotary connection, which is suitable for low frequency and general RF applications. It is commonly found in video surveillance, electronic equipment and laboratory measuring instruments.
N type connector
Type N connectors are suitable for higher power RF systems, commonly found in base station antenna systems and RF test equipment. It is available in two versions: N-type and N-type inverse interface (RP-N).
Threaded neill-concelman
The TNC connector is a transitional connector between BNC and N-type, using a threaded connection to provide better mechanical strength and a higher frequency range.
Ultra high frequency
UHF connectors, also known as PL-259 (plugs) and SO-239 (sockets), are mainly used in lower frequency radio frequency systems, such as car radios and some general communication applications.
F type connector
Type F connectors are commonly used in television antennas, cable television, and satellite television systems. It uses a threaded connection, suitable for lower frequency RF signal transmission.
SubMiniature version B
The SMB connector is a small version of the SMA, suitable for high-frequency applications, but due to its compact design, it is mainly used in relatively light applications, such as TV, radio and wireless communications.
Micro coaxial connector
MCX connector is a small coaxial connector, commonly used in portable devices and wireless communication equipment, with good frequency characteristics and connection performance.
Characteristics of RF Coaxial Connectors：
