Abstract
A new approach for linear amplification with nonlinear components (Z-LINC) that provides a zero capacitive load to their power amplifiers is proposed. The zero capacitive loading over the whole power back-off range enables to overcome the efficiency deterioration. The concept is theoretically and experimentally validated through a comparative study between fabricated classical LINC and Z-LINC prototypes.
