Intermodulation distortion optimization strategy based on active negative feedback in ultra-wideband low-power amplifiers

With the rapid development of communication technology, ultra-wideband amplifiers play an increasingly important role in modern communication systems. However, there are still many challenges to achieve high-efficiency amplifiers in a low-power environment, especially how to reduce intermodulation distortion. The study explores the working principle of ultra-wideband low-power amplifiers, and then conducts an in-depth analysis of the characteristics of active negative feedback technology and its impact on intermodulation distortion. Through experimental testing, the impact of different active negative feedback parameter configurations on amplifier performance was discussed around the experimental environment and equipment, experimental condition settings, and data collection and analysis. Based on the experimental results, three intermodulation distortion optimization strategies for ultra-wideband low-power amplifiers are proposed: spectrum analysis to locate the distortion source, a fine-tuning strategy for negative feedback depth, and scenario-specific gain and frequency adjustment. It is expected to further improve amplifier performance and realize efficient communication systems.
