  • Repeater and method for automatically setting output signal level of repeater
    Patent number: 7162201
    Abstract: 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 Vref; a comparison unit for comparing the detected voltage Vdec from the voltage detection unit and the reference voltage value Vref 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 Vref to be identical to the detected voltage Vdec and controlling an output of repeater based on the comparison result from the comparison unit after setting the output signal level of the repeater.
