Abstract: Provided is an intermediate-frequency analog-to-digital conversion device, including: a gain attenuation module, a gain amplification module, a filter and an analog-to-digital conversion module. The gain attenuation module is configured to perform attenuation processing on a received intermediate-frequency signal. The gain amplification module is connected to the gain attenuation module, and configured to perform amplification processing on a signal that is output from the gain attenuation module. The filter is a variable filter, connected to the gain amplification module, and configured to perform filter processing on a signal that is amplified by a gain amplifier. The analog-to-digital conversion module is connected to the filter, and configured to convert a signal that is filtered by the filter into a digital signal. The technical solution solves the technical problem in the related art and achieves the technical effect of improving the universality of the intermediate-frequency analog-to-digital conversion device.
