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(LoopFilter)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！----------------------------DESCRIPTIONThePT4302isanultra-lowpowerOOK/ASKsuperheterodynereceiverforthe315/434MHzfrequencybands.Itoffersahighlevelofintegrationandrequiresonlyfewexternalcomponents.ThePT4302c***istsofalow-noiseamplifier(LNA),adown-conversionmixer,anon-chipphase-lockedloop(PLL)withintegratedvoltage-controlledoscillator(VCO)andloopfilter,anOOK/ASKdemodulator,adatafilter,adataslicingcomparatorandanon-chipregulator.ThePT4302is***ailablein16-pinSSOPpackageandisspecifiedovertheextendedtemperaturerange(-40to+85°C).APPLICATI***•AutomotiveRemoteKeylessEntry(RKE)•RemoteControl•Garagedoorandgateopeners•Suitableforcircuitapplicati***thatmeeteithertheEuropeanETSI-300-220ortheNorthAmericanFCC(Part15)regulatorystanda***FEATURES•Ultra-lowpowerc***umption:2.7mAforfullyoperation(315MHz)•Fewexternalcomponents•ExcellentSensitivityoftheorderof–111dBm(peakASKsignallevel)•Supplyvoltagerangefrom2.4Vto5.5V•250MHzto500MHzfrequencyrange•Datarateupto10Kb/s--------------------PTC/普诚科技旗下还有以下射频芯片：PT4455/PT4301/PT4450/PT4316/PT4317/RX3310A都可以长期稳定优势供应！联系方式：***381331022，林先生，电话：0755-83678216，13924647173)
