Description
The AS230-348 is an IC FET SPDT reflective switch in a low-cost plastic package. It features extremely high linearity, low insertion loss, with very low DC power consumption. Some standard implementations include antenna changeover, T/R and diversity switching over 2 W. This switch can be used in many analog and digital wireless communication systems.
Exposed paddle should be grounded. DC blocking capacitors (CBL) are required on RF lines for positive voltage operation.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times.
All other conditions not recommended. VLOW = 0 to -12 V. VHIGH = 0 to 12 V. Differential = 5 V ( VHIGH- VLOW) < 12 V.
