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 wire-
less 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.
