The LINC (linear amplification using nonlinear components) transmitter shows considerable potential for use in future mobile radio systems employing spectrally efficient linear modulation formats. An experimental LINC transmitter that utilizes modern digital signal processing techniques to perform accurately the necessary signal component separation within the transmitter is described. A technique for significantly reducing the bandwidth required for this digital signal processing is outlined, and practical results which demonstrate that the linearity of the transmitter compares favorably with established linearizing techniques such as Cartesian feedback are presented
