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：

Good high-frequency transmission performance

RF coaxial connectors have excellent high-frequency transmission performance and can achieve high-quality high-frequency signal transmission. Because its internal structure adopts a coaxial structure, it can effectively reduce the loss and interference during signal transmission.

Stable connectivity

The connectivity of RF coaxial connectors is stable, with good mechanical and electrical performance, ensuring the stability and reliability of signal transmission quality. At the same time, it has a compact structure, is not easy to loosen, and can maintain a long-term stable connection state.

FAQ

 

Q: What is an RF coaxial connector?

A: An RF coaxial connector is a high-frequency interface for RF cable systems. It gives fast signal transfer, stable power flow, and low-loss performance. It also keeps strong shielding for clean RF transmission.

Q: What materials do you use for the connector body?

A: We use high-grade brass and stainless steel. Both materials give strong strength, stable RF results, and long service life. The surface stays smooth under long use.

Q: What plating options are available?

A: We offer nickel, gold, and silver plating. Each plating gives solid contact, high corrosion resistance, and clean signal flow. Gold plating gives the best long-term connection.

Q: Do your connectors have low insertion loss?

A: Yes. The design gives very low insertion loss. The performance stays stable across the full working band. This helps keep system power efficiency.

Q: What cable types are compatible with your connectors?

A: Our connectors match RG cables and low-loss cables. Examples include RG58, RG174, RG316, RG178, LMR200, and LMR400. We support flexible cable and semi-rigid cable.

Q: Are your connectors suitable for outdoor RF systems?

A: Yes. We offer IP-rated, weather-sealed, and corrosion-resistant connectors. The design handles rain, dust, UV light, and long outdoor exposure.

Q: What is the operating temperature range?

A: Standard models run from −40 °C to +85 °C. High-temperature models support +125 °C. The materials stay stable under strong heat or cold.

Q: Do you offer both 50-ohm and 75-ohm versions?

A: Yes. We supply 50-ohm and 75-ohm connectors for RF, telecom, and broadcast systems. Both versions give accurate impedance and clean signal output.

Q: What connector series do you offer?

A: We offer SMA, SMB, SMC, BNC, TNC, N-Type, F-Type, UHF, MCX, MMCX, QMA, and SMB mini. These models fit most RF equipment and cable systems.
