RF (radio frequency) connectors are connectors that are designed to work at radio frequencies for signal transmission of products like radios, antennas, coaxial cables, etc. An N-type connector is a kind of RF connector.
What is the function of N-type connectors?
How does the N-type connector work?
What is the advantage of an N-type connector?
The N-type connector is a small and medium power connector with a threaded connection mechanism. It is suitable for connecting radio frequency cables or microstrip lines in radio frequency loops of microwave equipment and digital communication systems. It can be interchanged with similar international NG products. It has the characteristics of wide frequency bandwidth, excellent performance, high reliability, and long life.
A properly designed N-type connector provides low-loss interconnection to 11 GHz, and an optimized accuracy version can provide accuracy up to 18 GHz. The screw coupling combined with a larger size (ie RG213) provides a sturdy design and suitable fitting for some larger coaxial cables. Applications include passive/active components used in broadcast electronics, aviation, telecommunications base stations, and base stations.
The peak power of the N-type connector has been determined by the breakdown/ionization of air voltage which is near the center pin. And the average rated power is determined by the overheating of the central contact due to the insertion loss of the resistor and therefore is a function of frequency. The typical curve of the manufacturer of the new connector specific to the required load (VSWR = 1.0) ≈ the derivatization rule at the square root frequency of 20 MHz and 2 GHz is caused by the skin depth decreasing with frequency. For low frequency, the upper limit recommended by the same manufacturer is ≈1000 V RMS. To ensure long-term reliable operation, it is not uncommon to adopt a safety factor of more than 5, especially when the common parts are replaced or the working environment may cause the contact to lose luster.
The N-type connector is a small and medium power connector with a threaded connection mechanism, which is suitable for connecting radio frequency cables or microstrip lines in the RF loop of microwave equipment and digital communication systems. It is widely used to connect RF coaxial cables to radio equipment and instruments and ground launch systems under vibration and harsh environmental conditions. It has the characteristics of high reliability, wide frequency bandwidth, long life, strong vibration resistance, and excellent mechanical and electrical performance.
Compared with the quick-lock type connector, the thread structure of the N-type connector is especially suitable for special applications. Such as requiring a very high degree of protection, or other connected products can not cope with the requirements of environmental factors such as temperature, pressure, or vibration. Because the threaded connection structure has the advantages of small size, lightweight, high contact couple density, and high reliability. Can be widely used. But screw-type connectors usually require longer installation time and do not support high-density connections. The specific structural form needs to be selected by the electrical engineer according to the needs.
Due to the development of modern industry, radio frequency connectors began to be mass-produced. N-type connector, as a kind of RF connector, has also become a basic component in modern communication products. LenoRF has been a trustworthy supplier in the RF connector area for many years. You will get the best quality products and the most intimate after-sales service which is beyond your imagination.
