Abstract
Linear amplification with nonlinear components (LINC) provide excellent linearity with high efficiency by adopting switch mode power amplifiers. One of the issues regarding LINC is the efficiency degradation due to wasted power at the power combiner when phase difference is large. In this paper, two efficiency enhancement architectures are presented: multi-level LINC (MLINC) architecture improves transmitter efficiency compared to a conventional LINC system, and the proposed uneven multi-level LINC (UMLINC) can further improve the efficiency. Another problem of LINC is the amplitude and phase mismatches between the two signal paths degrading the linearity performance. To address the problem, an unbalanced mismatch calibration technique for the proposed LINC system is introduced.
