Abstract
A transmitter includes: a first envelope extractor that extracts a first envelope signal on the basis of a first modulated signal of a first frequency modulated with transmission data; a second envelope extractor that extracts a second envelope signal on the basis of a second modulated signal of a second frequency modulated with the transmission data, the second frequency being higher than the first frequency; an amplifier that amplifies one of the first modulated signal and the second modulated signal; a power adjuster that outputs a voltage of power supplied to the amplifier; and a controller that makes the amplifier amplify one of the first modulated signal and the second modulated signal and makes the power adjuster output the voltage of the supplied power on the basis of corresponding one of the first envelope signal and the second envelope signal.
