PURPOSE: A microwave device including a function to store RSL(Receiving Signal Level) data is provided to mange the RSL, so as to periodically manage data for the level of inputted receiving signals in a receiving unit of the microwave device. CONSTITUTION: A transmission unit(100) performs frequency conversion for inputted modulation signals to have an ultra high frequency band, and outputs the frequency-converted modulation signals through a transmission antenna. A receiving unit(200) converts receiving signals received through receiving antennas into IFs(Intermediate Frequencies). A modulation and demodulation unit(300) performs QAM(Quadrature Amplitude Modulation) for inputted STM-1(Synchronous Transfer Mode-1) signals and RSL data signals, and demodulates IF signals from the receiving unit(200). A baseband unit(400) converts subscriber signals into STM-1 signals, and modulation signals from the modulation and demodulation unit(300) into subscriber signals, and generates RSL data based on the RSL of the receiving unit(200). Also, the baseband unit(400) outputs the RSL data by a predetermined cycle, and controls the modulation and demodulation unit(300) to transmit the RSL data. And a computer(500) stores the RSL data from the baseband unit(400).
