Embodiments of the present invention provide a device and a method for detecting a received signal strength indicator (RSSI). The method comprises: receiving a modulated signal data stream from a microwave sending end, and amplifying the modulated signal data stream according to an amplification control signal, the amplification control signal being used for indicating an amplification multiple of the modulated signal data stream; performing analog-to-digital conversion on the modulated signal data stream after amplification, to obtain a first digital signal data stream; filtering the first digital signal data stream; performing power detection on the first digital signal data stream, to obtain a first average power value; performing power detection on the first digital signal data stream after being filtered, to obtain a second average power value; obtaining the amplification control signal according to the first average power value; and calculating to obtain an RSSI value according to the amplification control signal and the second average power value. The embodiments of the present invention perform power detection on the entire bandwidth of the first digital signal data stream, thereby preventing jump of the amplification control signal. |
