Description
The SKY13251-349 is a PHEMT GaAs IC SP3T switch in a
2 x 2 mm QFN-8E package. The high isolation, low loss, small
size and low cost features make this switch ideal for isolating
Bluetooth® from 802.11b, g and designs that require combining
TDMA, GSM, EDGE, CDMA, WCDMA with other short-range wireless applications. This switch is also available in a lead (Pb)-free
package that is fully compliant with current RoHS requirements.
The SKY12351-349 employs an asymmetrical design for
improved performance as a transmit-receive switch. The path
between the RF common (RFC) and RF1 is optimized for low loss
transmit use, while the remaining two paths, RFC to RF2 and RFC
to RF3, are optimized to produce higher isolation in receiver
signal paths.
A fully populated evaluation board is available.

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.
