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 (C
BL
) 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 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.
All other conditions not recommended.
