Coaxial connectors are devices designed to provide a secure link between connections for radio frequency (RF) signals. Terminators are used with coaxial connectors to prevent signals reflected back from the end of the line into the coaxial line. This article will look into the application field and working principle of coaxial connectors and terminators in 202103.

Coaxial connectors find application in a wide range of RF applications including test and bench equipment, CATV, broadcast, microwave and satellite systems. In the 202103 application, coaxial connectors are used to ensure signals can be transferred without signal loss or interference.

Coaxial connectors use a two-part connector, consisting of a central conductor with a conductor around it. The central conductor is a solid metal or braid of conductive wire, while the conductor around it is a tubular-shaped material, usually metal. The inner and outer conductors of the coaxial connector are separated by an insulating material. This allows them to form an air-tight electrical connection, thus providing an RF-tight connection.

The working principle of coaxial connectors is based on the concept of impedance matching. This involves matching the impedance of the connector to the impedance of the signal being transferred. When the impedance of the connector and the signal are matched, the reflection of the signal is minimized. This reduces the amount of signal lost to resistive impedance mismatch. With this, the signals that are transmitted are more consistent and stable.

Terminators are used in conjunction with coaxial connectors to prevent reflections of signals back into the coaxial line. Terminators are placed at the end of the coaxial line to absorb the energy being sent back. This prevents problems caused by signal reflections, such as signal degradation or instability. Terminators are typically made of metal and can be either fixed or adjustable, depending on the application.

In 202103, the application and working principle of coaxial connectors and terminators remain the same as in previous years. The connectors and terminators provide a safe, secure link between RF signals, while the terminators absorb any reflections of signals back into the line. By using coaxial connectors and terminators, signal quality and stability can be improved, while eliminating signal loss and interference.
