Abstract: A signal processing device is provided. The signal processing device includes a proximal end device, a connection unit, and a distal end device. The proximal end device generates a first radio frequency signal. The connection unit is coupled to the proximal end device and receives and transmits the first radio frequency signal. The distal end device is coupled to the connection unit, receives the first radio frequency signal, performs a power detection on the first radio frequency signal to generate a detection signal, generates a control signal according to a comparison result of the detection signal and a predetermined reference value, and transmits the control signal to the connection unit. The proximal end device further receives the control signal through the connection unit, and adjusts the first radio frequency signal according to the control signal so as to generate a second radio frequency signal.
