Abstract
The present disclosure relates to signal sending circuits, signal receiving circuits, electronic apparatus, and base stations. One example circuit includes a signal pre-processing sub-circuit, a digital-to-analog conversion sub-circuit, an intermediate frequency power splitter, K frequency conversion phase-shift sub-circuits, and K antenna elements. An output end of the signal pre-processing sub-circuit is connected to an input end of the digital-to-analog conversion sub-circuit, an output end of the digital-to-analog conversion sub-circuit is connected to an input end of the intermediate frequency power splitter, an output end of the intermediate frequency power splitter is connected to input ends of the K frequency conversion phase-shift sub-circuits, and output ends of the K frequency conversion phase-shift sub-circuits are connected one-to-one to input ends of the K antenna elements.
