Abstract
AbstractIn this study, a special inverted Doherty topology and uneven power drive methods are proposed to optimize the efficiency and appropriate load modulation. The amplifier is optimized at large power back‐off. The power added efficiency and adjacent channel leakage ratio (ACLR) are 33.1% and −47 dBc, which improve by 3.2% and 5 dB, respectively, and its third‐order intermodulation distortion (IMD3) has 2 .5 dB improvement compared with conventional Doherty power amplifier. © 2008 Wiley Periodicals, Inc.
