Understanding the Features and Applications of N-Type Connectors

N-type connector is a common RF connector, widely used in wireless communications, RF systems and other high-frequency applications. It is known for its reliable signal transmission and excellent matching performance. N-type connectors have different impedance types, including the common 50 ohms and the special 75 ohms. This article will introduce the characteristics of the n-type connector, the scope of application and other connectors compared.

What is N Type Connector

The N type Connector is a standard connector commonly used in high frequency radio frequency applications. It uses internal thread structure, often used to connect between RF cable and equipment to achieve stable signal transmission and electrical connection. The N-type connector has reliable connection characteristics and good signal transmission performance, and is suitable for a wide range of operating frequencies.

Design and Construction

N-type connector adopts internal thread structure and has reliable connection characteristics. The utility model is composed of a central lead, an external lead, an insulator, a housing and a metal contact surface. The connection and fixing are realized through the threaded joint. This design can provide stable signal transmission and good shielding performance.


50 ohm n type connector

Is the most common and standard type N connector impedance type. It is suitable for most wireless and RF applications and provides reliable signal transmission and matching performance. It performs well in applications with a frequency range of 0-11 GHz.

75 ohm n type connector

This is a special type of n-connector impedance used for certain applications, such as video and broadcast equipment. Connectors that use 75 ohms need to ensure that the cables and equipment they are connected to also have the same 75 ohm impedance to ensure signal transmission compatibility and performance.

N Type Connector Types

N-type connectors come in many different types and are suitable for different applications and requirements.

N Type Female Connector

The N-type female connector has a center hole and an internal thread for connecting to the corresponding N-type male head.

Application area

N-type connectors are widely used in the following fields

  • Communication system: including wireless base station, antenna system, microwave transmission equipment.
  • Measurement and test equipment: for connecting RF test equipment, spectrum analyzer, signal generator, etc. .
  • Military and defense: Used in radar systems, navigation equipment, military communications equipment.
  • Aerospace: including navigation equipment, spacecraft communications equipment.
  • Medical equipment: including medical diagnostic equipment, medical image transmission equipment.
  • Industrial applications: Used in industrial automation equipment, wireless data transmission equipment.

Key features of N-type connectors

  • High frequency performance: suitable for a wide range of high frequency, providing stable signal transmission.
  • Reliability: reliable connection characteristics, able to withstand vibration and environmental pressures.
  • Low insertion loss: minimizes energy loss during signal transmission.
  • High reflection loss: reduce signal reflection, improve transmission efficiency.
  • Good shielding performance: resist electromagnetic interference, reduce signal interference and noise.
  • Multiple connection modes: flexible adaptation to different connection requirements and installation methods.

How to install an N-type connector

An easy way to install the N-connector is to strip the cable for an appropriate length, exposing the central conductor and the insulating layer. The central conductor is then inserted into the central lead hole of the connector, and the external lead of the cable is inserted into the external lead hole of the connector. Finally, fasten the connector housing to ensure that the connector is securely attached to the cable.



How does the type N connector differ from other common connectors such as BNC and SMA?

N-type connectors have a higher frequency range and better performance than BNC and SMA connectors and are suitable for higher frequency applications.


How to select the correct type and specification of N-type connectors?

Consider the frequency range, cable type, performance requirements, interface type, and special requirements. Refer to the supplier’s specification sheet and product description, or consult a professional or supplier for more advice and help.


What are the common failures and troubleshooting methods?

Common failures of type N connectors include loose connections, corrosion, and damage. Troubleshooting methods include checking connections for fastening, cleaning connectors, and replacing damaged connectors. Ensure that the stability and cleanliness of the connector can effectively solve common failure problems.


The N-type connector is suitable for those coaxial cables?

The N-type connector is suitable for many different types of coaxial cables, including common coaxial cables such as RG-58, RG-59, RG-6, and LMR series. They are commonly used in wireless communications, television antennas, RF devices, and other applications that require high-frequency transmission.


In a word, as an important RF connector, n-type Connector plays a key role in wireless communication and RF applications. When choosing and using N-type connectors, you need to determine the best option based on your specific application requirements and equipment requirements.
