Introduction to RF Ferrite Circulator Isolator
This Article shares about Introduction to the RF Ferrite Circulator isolator. RF Circulators and Isolators are defined as RF Ferrite components, that transfer RF signals by control of the ferrites. An RF signal experiences a low loss in the direction of the arrow and a high loss in reverse due to its non-reciprocal.
RF Circulators and Isolators non-reciprocal work on the magnetic fields. The RF signal can still be reciprocal in the magnetic fields without RF Ferrite. The resonant frequency was based on the RF Ferrite in the device.
The connection of RF Circulators:
RF Circulator is featured by its non-reciprocal in transmitting electromagnetic waves. The ideal insertion lossless N port Circulator only allows the electromagnetic waves from one port in, and all from the next port out.
A picture of the three-port circulator below, the electromagnetic wave input from port 1 can only be output from port 2, and input from port 3 can only be output from port 1.
Ideally, waves cannot go in reverse.
3-Port RF Circulator
The Applications of RF Circulators
Usually, a three-port circulator can be used as a duplexer. Port1 connects with the transmitter, Port2 connects to the antenna and Port3 connects to the receiver to achieve the purpose of sharing the same antenna.
In order to prevent the reflected electromagnetic wave from burning the receiver, when using it in a high-power system, it is quite common to connect a Limiter between the port3 and the receiver.
Another application of the circulator is to connect several circulators together to function as a parametric amplifier. For example, connect the three circulators together to the dummy load at the terminal.
The applications of RF Isolators:
When one port of the circulator connects with a matching load, the component can be used as RF isolator.
RF isolators are widely used in the protection of high-power RF generators in order to prevent the generator from being unstable or even burned due to load changes caused by reflected power. Use an isolator to take out the reflected power between the antenna and transmitter or between communication systems and the radar systems.
An RF isolator can also be used on the receiver port.

X-band RF Isolator and Circulator
The X-band belongs to the microwave frequency range. There are two versions of X-band: one refers to the radio wave band with a frequency of 8-12GHz, and the other refers to the frequency range of X-band with a frequency of 7-11.2GHz. This artical introduces some X-band RF isolators and circulators.
