Coaxial Connectors (RF)

Coaxial connectors are commonly used in radio frequency ( RF ) applications due to their high current and voltage capabilities, low losses, good immunity to electromagnetic interference, and relatively low cost. The 138-4416-007 is a standard coaxial connector designed for RF applications.

Application Field

138-4416-007 connectors are used in a variety of RF applications, including cellular phone and wireless communications, AM and FM broadcasting, satellite communications, broadcast television, microwave, RF power amplifiers, RF test equipment, navigation systems, automotive electronics, and medical equipment.

This type of connector is especially well-suited for cell phone and wireless applications, as it is capable of achieving low insertion loss, high return loss, and high power handling. It is also capable of operating over a wide frequency range from DC to more than 6GHz, making it ideal for applications requiring both low and high frequencies.

Working Principle

The 138-4416-007 connector is essentially a two-part system consisting of an inner and outer contact. The inner contact is usually made from brass or other electrically conductive material and consists of a central pin or tube and a number of concentric tubes. The outer contact is usually made from a dielectric material such as plastic or ceramic and is designed to provide insulation and a path for the electrical signal to flow.

The two contacts are held together by a metal shell, which allows the signal to pass between the two contacts without the interference from outside sources. The electrical connection between the inner and outer contacts is secure, resulting in a low impedance, low contact resistance, and high isolation characteristics.

The outer contact and the metal shell must be carefully constructed to ensure the connection is secure. The outer contact must be sealed to the shell with an O-ring or other sealant to prevent any air or moisture from entering the connection and causing corrosion.

The 138-4416-007 connector is a reliable and cost effective solution for many RF applications. It is resilient to environmental conditions, including dust, moisture, and vibration, and provides a secure connection for low and high frequency signals. As such, it is an ideal choice for RF applications such as cellular phones, wireless communications, and broadcast television.
