PT4302是专为低功耗及高接收感度无线传输控制需求所开发的芯片.
高整合度的设计,使得PT4302仅需少数几个被动组件配合即可工作,能减少电路板使用面积并缩短开发或样机制作的时间.
PT4302在设计上特别对功耗作了有效管控,在5V时,315MHz的操作电流少于3mA ,对于日益严格的环保需求或手持式产品提供了良好的解决方案.
PT4302内建高性能的低噪声放大器(LNA),整合压控震荡器(VCO)和回路滤波器(Loop Filter)的锁相环(PLL)及使用10.7MHz作为其中频,.
PT4302除省电省零件外,亦具有优异的接收感度和抗噪声能力.特别适合用于汽机车防盗，遥控卷门、灯具、窗帘等环境噪声较大的应用.
PT4302内建稳压器,可操作在2.4V~5.5V.包装型式则采用好加工的SSOP16小包装。
PT4302+PT4450目前是行业的选择的黄金担当配合！
