摘要：
This paper studies the impact of gain scaling on linearization performance and power added efficiency (PAE) of a power amplifier (PA) using digital predistortion (DPD). The performance of the DPD designed at different operating points of PA with different choices of gain are compared. An adjustment in iterative DPD identification procedure is proposed to improve the convergence. The performances are evaluated experimentally with a 500-W peak Three-way Doherty PA.
