N-type connector

N-type connector

N-type connector is one of the most widely used connectors because of its solid structure, which is often used in harsh working environments or in test fields that require repeated plugging. The working frequency of standard N-type connector is 11GHz as specified in MIL-C-39012, and some manufacturers produce it according to 12.4GHz; The outer conductor of the precision N-type connector adopts a non slotted structure to improve its high-frequency performance, and its working frequency can reach 18GHz.

SMA connector

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

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

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

TNC connector

TNC connector is close to BNC, and 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 have a standard operating frequency of 6GHz. Among the existing RF connectors, the DIN 7/16 connector has the best passive intermodulation performance. The typical passive intermodulation PIM3 of the DIN 7/16 connector provided by Shenzhen Rufan Technology Co., Ltd. is – 168dBc (@ 2 * 43dBm).

4.3-10 Connectors

4.3-10 connector is a reduced version of DIN 7/16 connector, and its internal structure and meshing mode are similar to DIN 7/16. The standard operating frequency of 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 Shenzhen Rufan Technology Co., Ltd. is – 166dBc (@ 2 * 43dBm).

3.5mm, 2.92mm, 2.4mm, 1.85mm, 1.0mm connectors

These connectors are named according to the inner diameter of their outer conductors. They adopt air medium and threaded mating structure. Their internal structures are similar, which is difficult for non professionals to identify.

The inner diameter of the outer conductor of the 3.5mm connector is 3.5mm, the standard operating frequency is 26.5GHz, and the maximum operating frequency can reach 34GHz.

The inner diameter of the outer conductor of the 2.92mm connector is 2.92mm, and the standard operating frequency is 40GHz.

The inner diameter of the outer conductor of the 2.4mm connector is 2.4mm, and the standard operating frequency is 50GHz.

The inner diameter of the outer conductor of the 1.85mm connector is 1.85mm, the standard operating frequency is 67GHz, and the maximum operating frequency can reach 70GHz.

The inner diameter of the outer conductor of the 1.0mm connector is 1.0mm, and the standard operating frequency is 110GHz. 1.0mm connector is the coaxial connector with the highest operating frequency at present, and its price is high.

The comparison between SMA, 3.5mm, 2.92mm, 2.4mm, 1.85mm and 1.0mm connectors is as follows:

Comparison of various connectors

Note: 1. SMA and 3.5mm connectors can be well matched, but it is generally not recommended to match SMA and 3.5mm connectors with 2.92mm connectors (because the pins of SMA and 3.5mm male connectors are thick, and the 2.92mm female connector may be damaged by multiple connections).

2. It is generally not recommended to match 2.4mm connector with 1.85mm connector (the pin of 2.4mm male connector is thick, and multiple connections may damage 1.85mm female connector).

QMA and QN connectors

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

QMA connector

The size of QMA connector is equivalent to that of SMA connector, and the recommended frequency is 6GHz.

The size of QN connector is equivalent to that of N-type connector, and the recommended frequency is 6GHz.

QN connector

SMP and SSMP connectors

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

SMP and SSMP connectors

It should be noted that the SMP male connector includes three types: optical hole, half escapement and full escapement. The main difference is that the mating torque of the SMP male connector is different from that of the SMP female connector. The full escapement mating torque is the largest, and it is the most tightly connected with the SMP female connector, which is the most difficult to remove after connection; The fitting torque of the optical hole is the minimum, and the connection force between the optical hole and the SMP female is the minimum, so it is easiest to take it down after connection; Half escapement is somewhere in between. Generally, the smooth hole and half escapement are suitable for testing and measurement, and are easy to connect and remove; Full escapement is applicable to situations where tight connection is required and once connected, it will not be removed.

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