As introduced before, RF circulators are used in a variety of RF circuit design applications. Usually, they tend to be used at microwave frequencies, so they are often called microwave circulators. Here, we will introduce two common applications of circulators. Duplexer: One of the most common applications for RF circulators is in radar systems or radio communication systems where the transmi……

The RF circulator has its own circuit symbol to facilitate its representation on electronic circuit diagrams or schematics. The basic symbol consists of a circle and an arrow, indicating the direction of the power cycle. Usually, the ports are shown in clockwise order around the circle: port 1, port 2, and finally port 3.If the component is done by counter-clockwise, it is marked in counterclockwi……
