Description
The AS218-321 is a broadband transfer switch designed to
combine T/R and antenna diversity switching functions on a
single IC. The device is designed to handle high power and
maintain high linearity at low control voltages. This low cost
switch is ideal for Wi-Fi systems and is capable of covering
both the 2.4 and 5 GHz bands.

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, Electrostatic Discharge (ESD) 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.
