Abstract
This paper presents a 2 GHz LINC transmitter demonstrator that generates a 16-QAM (Quadrature Amplitude Modulation) signal using switchable phase shifters fabricated on a low cost substrate (FR4, 1.6 mm, epsilon(r) = 4.6). The number of switch elements required has been reduced from 16 per branch to 6 per branch by a careful analysis of the complete set of combinations required. (C) 2002 Wiley Periodicals.
