Coaxial Connectors (RF) - Adapters

Adapters are a highly important component of a coaxial connector as they allow for the connection of two different types of cables to one another. The two main types of adapters used in RF applications are Type N and Type 7/16. Each type has its own unique application field and working principle which we will explore below.

Type N Adapters

Type N adapters are extremely common in the RF industry, and are usually used in a wide range of applications. They provide a very secure connection between two cables, as the threads are tightened with a wrench as opposed to relying solely on the force of the connector to keep the connection secure. This type of adapter is typically used in Ethernet cables, and can also be used for other communications equipment.

Type N adapters are one of the most durable adapters available, as the connector has very small tolerances which help prevent the cable from loosening over time. The adapter is also secured by the metal threads which are used to secure the connection, preventing any potential damage from the environment or from excessive force applied to the adapter.

Type 7/16 Adapters

Type 7/16 adapters are another important component of any RF connector system. These adapters are typically used in more specialized applications, such as satellite communications. One of the major differences between Type N and 7/16 connectors is the size of the threading. While Type N connectors have smaller threads, 7/16 connectors have much larger threads which provide a strong connection between two cables.

The 7/16 adapter has a higher strength rating and provides a superior connection than Type N adapters. The adapter also supports more frequencies and a larger bandwidth than Type N connectors. Furthermore, the adapter is able to better withstand environmental factors such as dust or moisture which could cause corrosion.

Conclusion

Both Type N and 7/16 adapters serve an important purpose in RF applications. Each type has its own unique application field and working principle, and must be selected with care to ensure that the appropriate connector is chosen for the application in which it is being used. By understanding the differences between the two and selecting the right type of adapter, a secure and reliable connection can be achieved.
