This switch has been designed for use where extremely high linearity, low insertion loss and ultraminiature package size are required. It can be controlled with positive, negative or a combination of both voltages. Some standard implementations include antenna changeover, T/R and diversity switching over 2 W. The AS188-92 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging. Electrical Specifications at 25 C (0, 3 V) (1) Parameter Frequency Min. Typ. Max.
