PURPOSE: A BTS(Base Station Subsystem) for a mobile communication system is provided to miniature a system by supplying a power with a radio frequency(RF) signal from a main BTS and a remote BTS. CONSTITUTION: A main BTS(300) has a transceiver(301) for performing a frequency upward conversion of a signal to be transmitted and converting the signal into an RF signal, an RF signal compensating unit(302) for compensating an attenuation of the converted RF signal, an RF signal control unit(303) for adjusting a level of the RF signal outputted from the RF signal compensating unit(302), a power supply unit(304) for outputting a power signal for a driving power, and a synthesizing unit(305) for synthesizing the RF signal of the RF signal control unit(303) and the power signal outputted from the power supply unit(304) to generate a single signal and transmitting the generated single signal to a remote BTS(310) through a same line. The remote BTS(310) has a dividing unit(313) for dividing the single signal transmitted from the main BTS(300) into an RF signal and a power signal, an RF signal control unit(311) for adjusting a level of the divided RF signal, an RF signal amplifying/compensating unit(312) for amplifying the RF signal outputted from the RF signal control unit(311) as a predetermined level or compensating an RF signal received from an antenna, and a power supply unit(314) for supplying a driving power needed for each device using the divided power signal.
