Coaxial circulators are passive devices that are used to isolate and protect sensitive electronic equipment from unwanted RF signals.

They are typically used in RF communication systems and in radar applications to protect sensitive receivers from transmitted signals.

A coaxial circulator consists of a three-port device that allows signals to flow in only one direction. The circulator contains a ferrite material that interacts with the RF signals passing through it to create the desired circulator action. This material is typically placed in a magnetic field generated by a permanent magnet or an electromagnet.

The three ports of a coaxial circulator are typically labeled as port 1, port 2, and port 3. Signals entering through port 1 can only exit through port 2, signals entering through port 2 can only exit through port 3, and signals entering through port 3 can only exit through port 1. In this way, the circulator ensures that signals are isolated and protected from unwanted interference.

Coaxial circulators are available in a range of frequencies and power handling capabilities to meet different application needs. They are commonly used in communication systems, satellite systems, and in military and aerospace applications.

Characteristics:

1. High reverse isolation: They can provide extremely high reverse isolation, which means that signals transmitted in one direction will not reflect in the other direction, thereby reducing signal loss and interference.
2. Low loss: Coaxial circulators have very low losses, which means they can provide efficient signal transmission without introducing excessive signal attenuation or distortion.
3.Strong power processing ability: They have high power load capacity and are not easily damaged.
4. Compact: Compared to other devices, their size is smaller, making them very suitable for applications in narrow spaces.

Fields:

1. Wireless communication: Wireless communication systems in the RF and microwave fields need to reduce noise and loss during signal transmission, and improve isolation. Therefore, coaxial circulators are widely used.
2. Radar: Radar systems require highly stable and reliable signal transmission, and coaxial circulators can provide this stable and reliable transmission.
3. Satellite communication: In satellite communication systems, coaxial circulators can help reduce signal loss and interference, thereby improving signal transmission quality.
4. Medical: Medical equipment needs to have highly stable and reliable signal transmission behavior. Coaxial circulators can provide efficient signal transmission for medical devices, reducing signal loss and interference.
5. Other application fields: In addition to the above application fields, coaxial circulators can also be applied in antenna systems, microwave communication, radar and other fields.
