The amplifier amplifies power of a transmission signal. The mixer unit mixes a feedback signal from the amplifier with a local signal of a predetermined frequency. The analog-to-digital converter performs analog-to-digital conversion on an output signal of the mixer unit. The distortion compensator compensates nonlinear distortion of the amplifier based on a digital signal obtained by performing the analog-to-digital conversion. The oscillator changes a frequency of the local signal to be mixed with the feedback signal in the first mixer in a time division manner, with frequency spacing corresponding to a sampling rate of the analog-to-digital converter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio apparatus","description":"To provide a radio apparatus including an amplifier, a first mixer, an analog-to-digital converter, a distortion compensator, and an oscillator.
