The PW3130 series product is a high integration solution for lithium-lion/polymer batteryprotection.PW3130 contains advanced power MOSFET, high-accuracy voltage detection circuits anddelay circuits. PW3130 is put into an ultra-small SOT23-5 package and only one external componentmakes it an ideal solution in limited space of battery pack. PW3130 has all the protection functionsrequired in the battery application including overcharging, overdischarging, overcurrent and loadshort circuiting protection etc. The accurate overcharging detection voltage ensures safe and fullutilization charging.The low standby current drains little current from the cell while in storage. Thedevice is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Polybattery-powered information appliances requiring long-term battery life

直接調制將基帶信號直接轉換為射頻信號,不需要二次頻率變換,與上變頻方式相比系統結構簡單,降低了對濾波器的要求,具有體積小,重量輕,成本低等明顯的優點.1/Q正交調制的關鍵指標是誤差矢量(EVM:Error Vector Magnitude).本文研究的是微波波段的直接調制技術。利用基帶對L波段和s波段幾個不同的載波進行直接調制。首先,在闡述1/Q正交調制基本原理的基礎上,通過對誤差矢量和鄰近信道功率泄漏的詳細分析,定性、定量地討論了各種非理想電路因素(如相位不平衡、幅度不平衡、直流偏差等)對調制器性能的影響;其次,介紹了鎖相環的工作原理和基本組成部分,包括鎖相環的設計和環路濾波器的設計,特別詳述了電荷泵鎖相頻率源;第三,介紹了采用直接調制技術模擬衛星信號的射頻前端的設計;最后,對整個直接射頻調制系統進行測試,結果基本上達到了課題要求。關鍵詞:微波鎖相環,相位噪聲,直接調制
