Abstract: PURPOSE: An apparatus for measuring transmitting power in a base station of a mobile communication is provided to measure average power of the mobile communication final output coupling signal through a diode attenuator and thus reduce an error due to change of peak power, thereby capable of measuring precisely transmission power of a base station. CONSTITUTION: A bandpass filter(2) receives a mobile communication final output coupling signal and performs a bandpass filtering. A frequency descending unit(DC) changes the output signal of the bandpass filter into an intermediate frequency signal. An SAW(Surface Acoustic Wave) filter(5) receives the intermediate frequency signal, then performs an SAW filtering and outputs only a signal of a specific channel which is supposed to be measured. An attenuator(6) attenuates the signal outputted from the SAW filter(5). An average power detecting unit(201) selects an input path of the mobile communication final output coupling signal outputted from the attenuator(6) and thereafter detects an average power. A peak envelope detecting unit(202) selects an output path by the control of the control unit(100), receives the average power outputted from the average power detecting unit(201), detects a peak envelope and then outputs the peak envelope to the output path. A reception signal amplifier(8) changes the reception signal received through the peak envelope detecting unit(202) into an analog voltage value corresponding to power intensity of a specific channel signal and then outputs the changed value. A control unit(100) receives an output signal of the reception signal amplifier(8) and then changes the output signal into a digital signal. The control unit(100) also calculates the digital signal and then outputs the intensity of the mobile communication final output coupling signal.
