Description
The AS225-313 is a 0.1–6 GHz PHEMT GaAs IC SPDT antenna
switch. Designed for WLAN applications, this device is capable
of switching 1 W microwave signals with 3 V control voltage
while maintaining high-linearity performance. The switch covers
the entire 802.11a, b and g frequency ranges. The low-loss, high-
isolation, high-inearity and low-cost features make this switch
ideal for Wireless LAN systems.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

Absolute Maximum Ratings
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 poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
