PURPOSE: A foldable RF remote unit is provided to be capable of easily replacing and testing any units mounted within a rack embedded in a system used in telecommunication. CONSTITUTION: When a PCB equipped in a bottom unit is replaced or tested, the bottom unit is rotated about a hinge(31) and opened to the same direction as a door(11) to be exposed by opening a rack door and pulling a top unit(30). Therefore, the PCB can be easily replaced and tested. When the test is completed, the top unit(30) is rotated to be mounted within a rack, At this time, a hook(32) of the top unit(30) is coupled to a coupling groove(13) formed on a bracket(12) equipped within the rack, whereby the top unit is fixed.
