Coaxial Connectors (RF)

2081203-3 Application Field and Working Principle

Coaxial connectors (RF) are a type of electrical connector designed specifically for use in radio frequency (RF) applications. Specifically, they are used in communications systems such as radio equipment, telecommunications, cable television, cellular phone, and radar systems. The 2081203-3 is one type of popular RF connector.

2081203-3 Overview

The 2081203-3 is a coaxial connector that features a 4-hole bayonet style locking system and a field replaceable version for applications that require frequent disconnects and reconnects. It is designed in a male-female configuration that has a 6.6mm center pin. It has a frequency range of DC to 10 GHz with a maximum voltage rating of 500Vrms. The 2081203-3 is commonly used in interconnections of radio and television transmitters, receivers, antennas, and other communication systems. It is also widely used in CATV systems including headends, distribution, NTR, and instalog systems.

2081203-3 Construction and Working Principle

The 2081203-3 connector consists of two mating parts. The male part has a center pin that is typically made from beryllium copper or phosphor-bronze and has a gold plated tip and ferrule. The female part has a dielectric rim and four outer contact fingers with spring action to ensure a positive electrical contact. The male part of the connector is inserted into the female part and locked in place using the bayonet locking system. The locking system is based on the principle of axial compression of the male part. Once the connections are secure, the center contact and the outer contact of the connector make an electrical connection, providing an uninterrupted signal path while preventing ingress from dust and other particles.

2081203-3 Advantages

The 2081203-3 connector provides a number of advantages over other types of RF connectors. First, it offers high performance with low insertion loss and return loss. Its 4-hole locking system provides superior electrical contact compared to screw-on connectors. Also, the 2081203-3 boasts an advanced sealing design that prevents the entry of moisture and other contaminants into the cable, helping to guarantee secure, reliable connections. Finally, the connector can be used in temperatures ranging from -40°C to 85°C, making it suitable for a variety of environmental conditions.

Conclusion

The 2081203-3 coaxial connector is a widely-used type of RF connector that is designed for use in radio, television, and other communications systems. It is designed in a male-female configuration and features a secure locking system that ensures reliable and uninterrupted signal paths. It offers low insertion and return loss, as well as advanced sealing to protect against moisture and dust. The connector is also suitable for use in a wide range of temperatures, making it an ideal solution for a variety of RF applications.
