DATA SHEET SKY13251-349, SKY13251-349LF: SP3T Switch for Bluetooth® and 802.11b, g Applications Simplified Block Diagram 802.11b, g ● Bluetooth® ● Zigbee™ ● TDMA/GSM/EDGE CDMA/WCDMA ● Other short-range wireless applications ● RF3 V3 RFC RF2 Features Positive low voltage control (0/+2.4 V) ● Low insertion loss (<0.5 dB @ 2.5 GHz) ● High isolation RF2, RF3 paths (29 dB @ 2.5 GHz and 27 dB @ 2.5 GHz) ● Miniature QFN-8 lead exposed paddle 2 x 2 mm ● PHEMT process ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 V1 ● RF1 NEW V2 Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging. 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. Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 200609 Rev.

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. Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 200609 Rev.
