DATA SHEET SKY13298-360LF: GaAs SP2T Switch for Ultra Wideband (UWB) 3–8 GHz Functional Block Diagram Features ● ● ● ● 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 Lead (Pb)-free and RoHS-compliant RFc J2 J1 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 VBIAS line enables the part 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 VBIAS is not required and is left open circuit on the board. NEW VBIAS VCTL1 VCTL2 Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

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.
