Coaxial connectors (RF) accessories such as the 221108-4 are essential components designed to make a secure connection between two devices. Such connectors are necessary for ensuring reliable and consistent data transmission when using radio frequency (RF) signals. This article describes the application field and working principle of the 221108-4 connector.

Application Field

The 221108-4 is a 75 Ω panel mount female connector with a threaded coupling nut and a hex crimp. It is mainly used for radio links and in various RF applications, such as base station transceivers, outdoor antennas, and other RF systems. The 221108-4 is also used in some automotive applications.

Working Principle

The 221108-4 connector derives its performance from its unique mating design. The contact inner of the connector uses a special circular groove which matches the outer conductor of a standard 50 Ω coaxial cable. When the nut is screwed, the contact of the inner and the outer conductor makes a perfect electrical connection. The contact ensures that the connection stays reliable even under vibration and high temperature.

Another benefit of the 221108-4 connector is its low insertion loss. The low insertion loss is due to the patented design of the contact which distributes the stress of the connection from time to time, thus minimizing any deformation of the connector. This results in better signal integrity, thereby improving the overall RF performance.

Conclusion

The 221108-4 connector is an essential component for making a secure connection between two devices. It is mainly used for radio links and in various RF applications. The unique mating design and low insertion loss of the connector makes it ideal for applications such as base station transceivers, outdoor antennas and other RF systems.
