摘　　要：文章从手持单端口矢量网络分析仪入手,探析了低功耗手持矢量网络仪动态优化方案。首先,阐述了系统设计理念与架构,分析了低速低功耗ADC实现大动态范围指标的难点。随后,围绕噪声源和算法控制2个层面,提出了相应的噪声抑制与算法设计等策略。通过实施这些技术措施,在降低设备功耗的同时成功保持动态范围不受影响,确保了产品性能的可靠性。相关成果不仅为手持矢量网络分析仪的设计提供了新的思路,而且为类似设备的低功耗优化提供了参考。This article starts with a handheld single port vector network analyzer and explores the dynamic optimization scheme of low-power handheld vector network analyzers.Firstly,the system design concept and architecture were elaborated,and the difficulties in achieving large dynamic range indicators with low-speed and low-power ADCs were analyzed.Subsequently,corresponding strategies for noise suppression and algorithm design were proposed around two levels:noise sources and algorithm control.By implementing these technical measures,the dynamic range is successfully maintained without being affected while reducing device power consumption,ensuring the reliability of product performance.The relevant achievements not only provide new ideas for the design of handheld vector network analyzers,but also provide references for low-power optimization of similar devices.
