PURPOSE: A satellite RF(Radio Frequency) transception signal distribution device is provided to offer a low RF data transmission service from launch of a satellite until the satellite reaches the normal orbit, and to offer a high-speed RF data transmission service after reaching the normal orbit. CONSTITUTION: An antenna unit(200) connects communication between a satellite and a ground station. An RF transception signal distribution unit(300) supports low-speed data transmission for normal orbit operation from launch of the satellite and high-speed data transmission in a normal orbit. A transponder unit(400) is connected to the RF transception signal distribution unit. The transponder unit transmits a signal applied from the RF transception signal distribution unit to the satellite or ground station.
