<p>According to an embodiment of the present invention, in a repeater having a down link, which processes an RF signal of a base station received from a donor antenna to be transmitted through a service antenna, and an up link which processes an RF signal of a terminal received from the service antenna to be transmitted to the donor antenna, a dual amplifier repeater according to one embodiment of the present invention includes a high power amplification unit at an end of at least one of the down link and the up link. The high power amplification unit comprises: a first amplifier having a first output; a second amplifier having a second output smaller than the first output; a switching unit which switches the RF signal inputted to the high power amplification unit to one of the first amplifier and the second amplifier; an output unit which outputs an RF signal, going through the first amplifier and the second amplifier; and a control unit which controls a switching of the switching unit.</p> |
