Coaxial Connectors (RF) are a type of electrical connector used to facilitate the connection of coaxial cable. The 142-0339-406 is a specialized series designed for microwave applications, and offers superior performance in high-frequency signal transmission. In this article, the application field and working principle of this series of connectors are reviewed.

Applications

The 142-0339-406 series of coaxial connectors are designed specifically for microwave applications. They are useful for applications involving frequency ranges between 2 GHz to 17 GHz, such as the transmission of digital or analog signals. They are often found in communication, telecom, satellite, and aerospace systems; scientific instrumentation, test measurement, and medical electronics; and high-level security and defense applications.

The advanced design of the 142-0339-406 series ensures excellent signal integrity with minimal data loss and superior shielding effectiveness. Additionally, they are compatible with a wide variety of cable types such as RG-174/U, RG-316/U, FLU-0.9 SF/U, and more, as well as other standardized coaxial interfaces. This makes them an ideal choice for a wide range of applications.

Design and Working Principle

The structure of the 142-0339-406 series consists of a center pin or terminal surrounded by an insulating dielectric material, which is then encased in a tubular metal shell. In this configuration, the separator, or distance between the center pin and the shell, is tightly controlled, which helps to maintain signal integrity and ensure minimum data loss. The design of this connector also ensures excellent shielding effectiveness through its double-walled construction.

These connectors are also designed with high-precision machining to achieve high-level interconnectivity. Their mating surfaces are carefully sculpted to ensure precision and durability, and the center contact is forced against the plunging surface of the mating part to ensure secure and reliable connections. Additionally, the arrangement of the contacts and the surface plating ensure superior performance when handling high-frequency signals.

Conclusion

The 142-0339-406 series of coaxial connectors are primarily used for high-frequency signal transmission, such as in microwave applications. They offer excellent shielding, signal integrity, and precision, which makes them well-suited for a wide range of communication, telecom, satellite, aerospace, scientific instrumentation, and high-security applications. As such, they offer superior performance when compared to other types of connectors.
