The switch is manufactured using the Skyworks state of the art pHEMT process. This is a general purpose switch that is optimized for a variety of multimode applications such as GSM/WCDMA/EDGE. The SKY14151 features integrated logic that uses only two control lines for the switch operation. The low current consumption of SKY14151 makes it suitable for battery-operated applications. This part comes in an industry-standard 3 x 3 mm 16-pin QFN package that is lead (Pb)-free and RoHS-compliant. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging. Preliminary Data Sheet: Based on engineering results. Sampling quantities available.
