Abstract
An analog pre-distortion processing circuit and a signal processing device, the analog pre-distortion processing circuit comprises a narrowband spread spectrum module, an analog pre-distortion module and a filtering module. The narrowband spread spectrum module is used for spreading an input narrowband radio frequency signal into a broadband radio frequency signal. The bandwidth of the broadband radio frequency signal is a preset bandwidth. The analog pre-distortion module is used for carrying out analog pre-distortion linearization processing on the broadband radio frequency signal to obtain a linearized broadband radio frequency signal; the preset bandwidth is located in the optimal cancellation bandwidth of the analog pre-distortion module. The filtering module is used for carrying out signal filtering on the linearized broadband radio frequency signal to obtain a linearized narrowband radio frequency signal.
