摘要：PURPOSE: An automatic gain controller for a BTS(Base Transceiver Station) is provided to improve receiving sensitivity and reliability by automatically controlling a gain of a receiving terminal. CONSTITUTION: A signal process unit(200) receives a signal of a mobile communication terminal or a single frequency signal through an antenna(1), processes the received signal, and outputs an alarm signal and an RF(Radio Frequency) according to the processed result. A low noise amplification gain control unit(300) receives the RF signal of the signal process unit(200), detects an amplification gain as a level of the RF signal, and uniformly maintains an amplification gain of the signal process unit(200) using the detected amplification gain according to a control signal of a control block(12). The control block(12) senses whether a signal of the antenna(1) is received, and controls an operation of the low noise amplification gain control unit(300) according to a test mode or a normal mode for remotely controlling the signal process unit(200).
