Zusammenfassung: | The invention provides a radio frequency receiving device with automatic gain control and a signal processing method thereof. A filtering module of the radio frequency receiving device is used for filtering a radio frequency signal to generate a filtering signal. An amplifier of the radio frequency processing module amplifies the filtered signal to generate a radio frequency output signal. The detection circuit detects the filtering signal to generate a detection signal. The control unit generates an intensity signal according to the detection signal and determines the detection signal to generate an automatic gain control signal. The control unit transmits the automatic gain control signal to the automatic gain control circuit, so that the automatic gain control circuit controls the radio frequency output signal of the amplifier according to the automatic gain control signal. The control unit transmits the intensity signal to the display unit, so that the display unit turns on and off the illuminator accordi |
