Nettet21. des. 2024 · Abstract: 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. NettetThe linearized amplifier demonstrates a state-of-the-art power-added efficiency (PAE) of 57.4% under W-CDMA criteria, resulting from a 5-dB reduction in adjacent channel leakage power ratio. In addition, the use of power control in a W-CDMA system requires amplifiers with good efficiency over a wide range of output power. cool coloring sheets for kids https://zohhi.com
