Coaxial Connectors (RF) Overview

Coaxial connectors (also known as RF connectors or electrical connectors) are an essential component in any electronic design, as they enable the connection of electrical signals from one device to another. In particular, RF connectors are designed to operate in harsh environments, and are used to connect radio-frequency signals, such as those from an antenna, to a receiver.The 3-1478978-0 connector is a typical example of a coaxial connector. It is a Multi-Function connector with 10A current rating and a maximum RF power of 6GHz. It is an ideal connector for use in high speed, high frequency applications.

Coaxial Connector Design

Coaxial connectors are designed to have a perfect impedance match between the device and the cable that connects them. This is achieved by having the centre and outer contacts both connected to the same metal cylinder, which forms the conductive shield. This shielding reduces interference and ensures that the signal is contained in the connector, preventing any undesired emissions.The connectors are also designed with a mechanical latch to ensure a reliable connection. This latch is formed by the outer contact being threaded into place, and a spring-loaded sleeve that compresses as the outer contact is twisted, securing the connection.

3-1478978-0 Application Field and Working Principle

The 3-1478978-0 is commonly used in high speed data and video transmission applications, where its reliable connection is able to maintain high signal quality, even in the presence of environmental noise and interference.The 3-1478978-0 is a 50 Ohm connector, which makes it ideal for transmitting radio frequency signals up to 6GHz. As the centre and outer conductors are connected, the signal is grounded within the connector, while the large 10A current rating ensures that it can handle large signal currents.The working principle of the 3-1478978-0 is based on the principle of impedance matching. It is designed to have a perfect impedance match between the transmit and receive side, which minimises signal interference and ensures a reliable connection. The mechanical latch of the connector also provides a secure fit, reducing the chances of any interference from vibrations and motion.
