An RF Isolator is used to block reflected and unwanted signals from entering a system. It is a two port device that allows the signal to flow from the Input port to the Output port with minimal loss, however isolates any signal that comes in from the Output port. RF Isolators play an important role in rf systems. Isolators are usually made of ferrite and magnet material.
The following parameters can be used to select an RF Isolator for your system:
1. Frequency (MHz): This is the frequency at which the rf isolator work
2. Isolation (dB): The level of Isolation from the output port to the input port. This is the most important parameter of an RF Isolator.
3. Insertion Loss (dB): This is the signal loss from the input to the output port. This is usually very low.
4. Power (W): There are two types of power forward and reverse. The forward power is the level of power the Isolator can handle from the Input to the output and the reverse power is the level of power it can handle from the output to the input.
5. Package Types: You can select from plug in isolators, surface mount isolators or connectorized isolators.
