Abstract: A wireless signal digital conversion device includes: a plurality of RF signal processing units for receiving wireless signals, and adjusting the voltage levels of the wireless signals based on automatic gain values; a plurality of unit ADCs for receiving in-phase signals and quadrature phase signals of the RF signal processing units, and performing analog-to-digital conversion based on different differential reference voltages; an encoder unit for generating binary data having less bits than binary data outputted from the unit ADCs based on the binary data outputted from the unit ADCs; and an automatic gain control unit for generating automatic gain values based on the output of a spatial ADC. A terminal can be linked to an artificial intelligence module, a drone (unmanned aerial vehicle (UAV)), a robot, an augmented reality (AR) device, a virtual reality (VR) device, a device related to 6G services, and the like.
