Filter separating (FR)

The FR is designed for connection of termination equipment of two or more different HF channels to one connection device. The FR has a high input impedance in the operating frequency band of the parallel HF channel. The FR prevents shunting of the HF channel by the parallel connection scheme; the FR prevents shunting of the HF channel as a result of damage to the equipment connected to the output of the FR or erroneous actions of the operating personnel; the FR prevents saturation of the transformers of the HF interface of the equipment with industrial frequency current
