A repeater and method for automatically setting output signal level of the repeater is disclosed. The repeater includes: a voltage detection unit for measuring a voltage of signal amplified by a plurality of the amplifiers; a digital variable resist unit for providing a reference voltage value V; a comparison unit for comparing the detected voltage Vfrom the voltage detection unit and the reference voltage value Vfrom the digital variable resist unit; and a control unit for setting output signal level of the repeater by controlling the digital variable resistor unit to generate the reference voltage Vto be identical to the detected voltage Vand controlling an output of repeater based on the comparison result from the comparison unit after setting the output signal level of the repeater.

A switchable combiner and apparatus for providing intergrated combiner unit, which can reduce problem due to frequent substitution of unit. The apparatus for providing intergrated combiner unit includes the means of; a) dividing input signal according to basic type, redundancy type or power division/coupling type; b) switching the transmitted signal to power amplifier; c) switching the transmitted signal to the means of combining; and d) combining the transmitted signal according to basic type, redundancy type or power division/coupling type.
