Coaxial Connectors (RF)

A RF coaxial connector is an electrical connector that utilizes a circular type of electrical connector made of a solid conducting center wire surrounded by a conducting cylindrical shield and insulated from the shield. Coaxial connectors are usually used for antenna, data transmission or broadband applications, and serves to attach a radio frequency signal from a source such as a wireless antenna to a receiving device.

122389 Application Field and Working Principle

The 122389 RF coaxial connector is an SMA (Sub Miniature) type connector used for RF/microwave/antennas applications. It is especially suitable for sharing signal in devices due to its high frequency and small size. It has a frequency range between DC~18GHz and a maximum power of 1.5W. It has a threaded coupling mechanism that offers speeds 2-3 times faster than traditional plug and socket-type connectors.

The 122389 coaxial connector has two main parts: the center contact and the outer shield, and each part contributes to its functionality. The inner pin is the actual conduit for the RF signal and it is connected directly to the thread on the body of the connector. The outer shield, also referred to as the outer barrel, acts as an insulator and protects the internal circuitry from outside RF interference and noise. By keeping the inner conductor and the outer shield connected, it ensures both low-voltage and high-voltage signals are kept away from each other, thus prevent cross talk.

The 122389 coaxial connector is designed with a quick connect and disconnect function and can be easily removed by rotating and unlocking its threaded fastener. It also has a built-in strain relief preventing cables from breaking due to over bending or stretching. This makes it easy to have a low-profile connection by connecting two units side-by-side while preventing the strain from over tightening the connection.

The 122389 coaxial connector is ideal for antenna, communication, instrumentation, measuring and monitoring applications, as the low insertion loss and high isolation it provides can ensure high-performance signal integrity. It is also designed for durability and reliable performance, which make it an ideal choice for both indoor and outdoor applications.
