Basic Introduction of RF Isolator
RF isolator is a kind of protection device in RF circuit. It is mainly used in the place where the front and rear end standing wave is poor. For example, the common application is at the output end of power amplifier. Because the output end of power amplifier is generally connected with the antenna end, in order to avoid the power reflected back from the antenna end burning down the amplifier, the isolator is connected at the output end of the power amplifier and the input end of the antenna.
The direction of the isolator can be selected according to the designed installation direction. The absorption and reflection power of the isolator is realized by the load power resistance connected to it.
