RF High Power BroadBand Power Amplifier Coaxial Isolators

Coaxial isolators are passive RF devices used to prevent reflected signals or signals in the reverse direction from flowing into sensitive electronic equipment or back into a transmitter.

They are commonly used in RF communication systems and in microwave applications to protect amplifiers, filters, and other sensitive electronic components from damage caused by reflected power.

A coaxial isolator is similar to a coaxial circulator and consists of a three-port device that only allows signals to flow in one direction. However, the isolator does not provide the circulator action and only allows signals to flow in one direction.

The three ports of a coaxial isolator are typically labeled as input port, output port, and isolation port. The input signal enters through the input port, travels through the isolator, and exits through the output port. Any reflected signal or signal in the reverse direction is dissipated in the isolation load at the isolation port, preventing it from flowing back into the input port.

Coaxial isolators are also made with a ferrite material and are typically placed in a magnetic field generated by a permanent magnet or an electromagnet. They are available in different frequency ranges and power handling capabilities to meet different application needs.
Overall, coaxial isolators are important for preventing damage to sensitive electronic equipment and ensuring the proper functioning of RF communication systems.
