Coaxial Connectors (RF)

The 142-0594-406 Coaxial Connector is a special type of RF connector primarily used in radio frequency (RF) applications. It is a connector designed with a central contact surrounded by a large metallic cylinder or shield, thus providing a ground return path. It is designed to prevent interference between transmission paths, allowing it to be used in environments where electromagnetic interference is a major concern.

Application Areas

The 142-0594-406 Coaxial Connector is primarily used in two primary application areas—communications and broadcast systems. It is used in both professional and consumer applications, including TV, satellite communications, two-way radio systems, radar systems, and microwave/millimeterwave networks. In addition, the connector is also used in test and measurement applications such as oscilloscopes, spectrum analyzers, and high-frequency signal generators.

Design Parameters

The 142-0594-406 Coaxial Connector is designed with an impedance of 50 ohms. It has a frequency range of 9 kHz to 3 GHz and VSWR (Voltage Standing Wave Ratio) better than 1.2:1. It is designed with an insertion loss performance of less than 0.2 dB, return loss at 95 dB, and dielectric withstanding voltage rating of 1kV. The power rating of the connector is 200W and connector interfaces are typically SMA, TNC, and SSMA because of their high performance characteristics. The connector size is 1.25 inches (3.17 cm).

Installation and Maintenance

The installation and maintenance of the 142-0594-406 Coaxial Connector are relatively easy. Though soldering is recommended for best performance, the connector has a crimp mode that does not require soldering. It is important to use the correct type of crimp tool to make the connection. To ensure optimal performance, careful attention needs to be given to the type of cable used, as well as the condition of the contact surfaces. Maintenance should be performed as needed, such as regular inspection and cleaning, to ensure that the connection remains in working order.

Working Principle

The working principle of the 142-0594-406 Coaxial Connector is based on providing an excellent electric path between two elements of an RF circuit. It is designed to resist the ingress of electromagnetic noise and provide an optimum return loss. The design and materials used in the connector help to minimize losses and ensure a good transfer of energy between two circuits. The connector also provides DC continuity between the two elements of a circuit, thus allowing power to be transmitted and maximized.

Conclusion

The 142-0594-406 Coaxial Connector is a high-performance connector designed to provide a reliable connection in a wide range of RF applications. It is designed to perform optimally in the presence of high levels of electromagnetic interference. By providing an excellent electric path between two elements of an RF circuit, it helps to minimize losses, while ensuring a good transfer of energy between the two circuits. Its design parameters, such as impedance, frequency range, VSWR, insertion loss, and power rating enable it to provide superior performance in its application areas.
