What is Coaxial Connectors

Coaxial connector refers to the part used to connect the ends of two shafts to ensure that the centerlines of the two shafts are on the same axis. It is generally used to connect the driving shaft and the driven shaft to transmit the rotating motion of the driving shaft to the driven shaft. 1). General coaxial connector 2) Dual coaxial connector 3) Triaxial connector 4) High voltage coaxial connector 5) PCB coaxial connector, 1) General coaxial connector 2) Dual coaxial connector 3) Triaxial connector 4) High voltage coaxial connector 5) PCB coaxial connector, 1) Electrical characteristics: wave impedance, cut-off frequency, return loss, insertion loss, operating voltage, insulation impedance, dielectric constant, 2) Mechanical characteristics: insertion and pull-out force, terminal retention force, durability,3).

Introduction to common coaxial connectors I

N-type connector

The n-type connector is one of the most widely used connectors because of its firm structure and is often used in harsh working environments or test fields requiring repeated plugging. The operating frequency of standard n-type connector is 11GHz specified in Mil-C-39012 standard of the US Army, and some manufacturers also produce it according to 12.4ghz standard; The outer conductor of precision n-type connector adopts non slotted structure to improve its high-frequency performance. Its working frequency can reach 18GHz.

SMA connector

SMA connector originated in the 1960s. It is the most widely used connector in the microwave and RF industries. The inner diameter of the outer conductor is 4.2mm and filled with PTFE medium. The operating frequency of standard SMA connector is 18GHz, while that of precision SMA connector can reach 27ghz.

SMA connector can be mechanically matched with 3.5mm and 2.92mm connectors.

BNC connector

BNC connector originated in the 1950s. It is a bayonet connector, which is easy to plug and unplug. At present, the working frequency of the standard BNC connector is 4GHz. It is generally considered that electromagnetic waves will leak out of its slot after exceeding 4GHz.

TNC connector

TNC connector is close to BNC. The greatest advantage of TNC connector is its good seismic performance. The standard operating frequency of TNC connector is 11GHz. The precision TNC connector is also called TNCA connector, and the operating frequency can reach 18GHz.

Din 7/16 connector

Din7/16 connector) is named after the size of this connector. The outer diameter of the inner conductor is 7mm and the inner diameter of the outer conductor is 16mm. DIN is the abbreviation of Deutsche industries norm (German industrial standard). Din 7/16 connectors are large in size and operate at a standard frequency of 6GHz. Among the existing RF connectors, DIN 7/16 connector has the best passive intermodulation performance. The typical passive intermodulation PIM3 of DIN 7/16 connector provided by Ningbo FBELE Company is -168dbc (@2*43dbm).

4.3-10 connector

4.3-10 connector is a reduced version of DIN 7/16 connector, and its internal structure and engagement mode are similar to DIN 7/16. The standard operating frequency of the 4.3-10 connector is 6GHz, and the precision 4.3-10 connector can operate to 8GHz. 4.3-10 connector also has good passive intermodulation performance. The typical passive intermodulation PIM3 of DIN 7/16 connector provided by NINGBO FBELE ELETRONICS CO., LTD. is -166dbc (@2*43dbm).

QMA and QN connectors

Both QMA and QN connectors are quick plug connectors, which have two main advantages: first, they can be connected quickly, and the time to connect a pair of QMA connectors is far less than that to connect SMA connectors; Second, the quick plug connector is suitable for connection in narrow space.

SMP and SSMP connectors

SMP and SSMP connectors are polar connectors with plug-in structure, which are commonly used in the circuit board of miniaturized equipment. The standard operating frequency of SMP connector is 40GHz. SSMP connector is also called mini SMP connector. Its size is smaller than SMP connector, and its working frequency can reach 67ghz.

It should be noted that the SMP male connector consists of three types: smooth hole, semi escapement and full escapement. The main difference is that it has the different mating torque with the SMP female head. The full escapement has the largest mating torque, and it is the most tightly connected with the SMP female head, which is the most difficult to remove after connection; The fitting torque of the smooth hole is the smallest, the connection force between the smooth hole and the SMP female head is the smallest, and it is the easiest to remove it after connection; Half escapement is somewhere in between. Generally, the light hole and half escapement are suitable for test and measurement, and are easy to connect and remove; Full escapement is applicable to the situation where tight connection is required and once connected, it will not be removed.

SSMP male connector includes two types: smooth hole and full escapement. The full escapement is equipped with a large relay moment, which is the most tightly connected with the SSMP female head, so it is not easy to remove it after connection; The fitting torque of the smooth hole is small, the connection force between the smooth hole and the SSMP female head is the smallest, and it is easy to remove after connection.

What does customer say about FBELE Company


We saw FBELE on the forum. At that time, we thought that the enterprise’s technical articles were very thorough and in-depth, and its social responsibility was also strong. This year, we just need to have new product development, so we found fbele and asked them to purchase samples. The speed was very fast and the quality was good, waiting for the implementation of the project!


At the beginning of our new project, we encountered some difficulties because we found several other unprofessional Chinese manufacturers. Since we contacted fbele, the project has been promoted rapidly. We have to say that FBELE’s technical team is really strong. Thank FBELE’s technical team.
