DATA SHEET SKY13298-360LF: GaAs SP2T Switch for Ultra Wideband (UWB) 38 GHz Functional Block Diagram Features RFc Positive voltage control (0/1.8 V to 0/3.3 V) High isolation 25 dB for BG1, 25 dB for BG3 Low loss 0.7 dB typical for BG1, 0.9 dB for BG3 J 2 J 1 Lead (Pb)-free and RoHS-compliant Description The SKY13298-360LF is a pHEMT GaAs FET IC switch packaged in an 2 x 2 mm, 8-lead exposed pad plastic package for low-cost commercial applications. The use of the V line enables the part BIAS V V V BIAS CTL1 CTL2 to be used with low control bias voltages down to 1.8 V. This switch is ideal for Ultra Wide Band (UWB) applications covering BG1 and BG3. For 3.3 V control, the V is not required and is left BIAS open circuit on the board. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

BIAS Any state other than described in the truth table will put the switch in an undefined state. 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 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. Skyworks Solutions, Inc.
