A2×1LINC Transceiver for Enhanced Power Transmission in Wireless Systems

摘要

A2×1LINC transceiver based on linear amplification using nonlinear components (LINC) architecture for wireless systems applications is proposed. The layout of the new architecture is presented and the simulation results show that the overall power efficiency of this architecture is superior by more than 300% when compared with that of a regular LINC amplifier. Also the adjacent channel power ratio (ACPR) is lowered to?64.2dBc, compared to?26.1dBc for regular LINC, which improves the system immunity against complex gain imbalances between LINC branches.
