Mobilephonechipsgenerallyrefertochipsusedinmobilephonecommunicationfunctions,includingbaseband,processor,coprocessor,RF,touchscreencontrollerchip,memory,wirelessICandpowersupplyManagementIC,etc.Atpresent,themainmobilephonechipplatformsincludeMTK,ADI,TI,AGERE,ST-NXPWireless,INFINEON,SKYWORKS,SPREADTRUM,Qualcomm,etc.
Classification
ThedomesticGSMseriesmobilephonescanbedividedintoeightplatforms:MTK,ADI,TI,AGERE,PHILIPS,INFINEON,SKYWORKS,andSPREADTRUM:
1.MTKchip(MediaTekInc.)
1.MTKchipisaseriesofproductsofMTK(MediaTekInc.),MTKplatformItissuitableforlow-endandlow-end,andthebasebandisrelativelyintegrated.Atpresent,mostofthedomesticcomputersuseitschips,especiallythosewithMP3andMP4atleast70%useMTKchips.
2.Themainbasebandchipsare:MT6205,MT6217,MT6218,MT6219,MT6226,MT6227,MT6228
