Description
The AS197-306 is a reflective SP2T and SP3T switch. It includes a four-line decoder to minimize the number of control lines. There are two separate output ports that can be diplexed for low and high band paths. Typical application is to use the SP2T for GSM Tx/Rx and the SP3T for WCDMA and DCS band Tx/Rx.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty.
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.
"0" = 0 to 0.7 V. "1" = 2.3 to VP. VP = 2.7 to 5 V. VP voltage must be applied prior to VCTL voltage.
