Repeater and method for automatically setting output signal level of repeater

摘要

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_ref; a comparison unit for comparing the detected voltage V_dec from the voltage detection unit and the reference voltage value V_ref from 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 V_ref to be identical to the detected voltage V_dec and controlling an output of repeater based on the comparison result from the comparison unit after setting the output signal level of the repeater.
