FIELD: information technology.
SUBSTANCE: radio signal generator with digital lineariser consists of a quadrature modulator, two analogue-to-digital converters, a digital signal processing unit and a digital lineariser, wherein a digital data signal is transmitted to the input of the digital signal processing unit, and two binary combinations are formed at the outputs of the digital signal processing unit, said combinations determining the phase and amplitude of the radio signal generated by the generator.
EFFECT: reduced distortions arising from nonlinearity of the amplification path of a radio transmitter, broader functionalities of the radio signal generator as a component part of a radio transmitter.
