What is an N-Type connector ?
The N-type connector, usually known simply as the N connector, is a precision RF coaxial connector that is intended to offer a dependable connection for radio frequency (RF) and microwave applications. It was invented by Paul Neill of Bell Labs in the 1940s, thus the designation "N" connection.
N connections are widely used in telecommunications, wireless systems, antennas, and laboratory test sets, with outstanding performance up to 11 GHz (or even 18 GHz for precision versions).
How Does an N-Type Connectors Work?
An N-type connector provides a reliable and low-loss connection between coaxial cables or RF components. It has a threaded coupling mechanism for a secure and weather-resistant fit.
The connector maintains the typical impedance (50 or 75 ohms) throughout the connection, which is critical for eliminating signal reflections and ensuring constant transmission quality.
When connected, the inner wire on one side establishes solid contact with the female socket on the other, while the outside conductor provides grounding and shielding, reducing signal interference and leakage.
Types of N-Type Connectors :
1. Standard N-Type (M) Connector (50 Ohm) :
- The most popular variant is intended for broad RF applications up to 11 GHz.
- Offers reduced VSWR and excellent mechanical performance.
Applications: Include antennas, base stations, RF amplifiers, and test devices.
2. 75 Ohm N-Type Connector :
- Optimized for video and broadcast applications with a typical 75-ohm impedance.
- Used for digital video transmission and CATV systems.
3. Standar N (F) Connector (50 Ohm) :
- The design is similar to ordinary N connections, except the male/female contact orientation is inverted.
- Commonly used in wireless networking to meet regulatory antenna connection requirements.
Applications: Include Wi-Fi routers, IoT devices, and WLAN networks.

4. Panel-Mounted N Connector :
- Designed to be placed on a panel or chassis, ensuring a solid and consistent RF interface.
Applications: Include equipment enclosures, telecom panels, and instrumentation systems.
5. Waterproof N Connector (IP67/IP68 Rated) :
- Features O-ring seals and gaskets are used to prevent water and dust infiltration.
- Suitable for outdoor antennas and hard environmental applications.
6. Right-Angle and Crimp-N Connectors :
- Right-angle designs conserve space, while crimp-type connections make field installs easier.
Applications: Include compact enclosures, RF test components, and bespoke cables.
