![TB20R0: IF Separation terminal (Reception) [6345R]](../images/system/R_6345R_TB20R0_web.jpg)
This is a device used for the transmission and the reception separation station in the relay station. It mixes analog-IF and digital-IF signal that has been inputted from the reception conversion part, and sends it to the transmission part. And, it separates standard reference signal (10MHz), and outputs it as the reference signal of the reception part. Besides, this device separates AC60V power and converts to the power supply of the reception part.
