DATA SHEET SKY13296-340LF: GaAs SP4T Absorptive Switch 20 MHz–2.5 GHz Functional Diagram Features ● ● ● ● ● ● Positive voltage control (0/3 V to 0/5 V) High isolation 35 dB at 1 GHz Integrated silicon CMOS driver Isolated ports are absorptive Use of external DC blocks to allow good return loss to low frequency Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 RFc J4 External Floating Caps External Floating Caps J3 Description The SKY13296-340LF is a pHEMT GaAs FET IC high isolation, absorptive single-pole four-throw switch packaged in a lead (Pb)-free, 4 x 4 mm, 20-lead exposed-pad plastic package for low-cost commercial applications. The use of external DC blocking capacitors on the RF ports and in series with the internal RF terminations enables the user to extend the range of good return loss to arbitrarily low frequency. This switch is an ideal building block for filter bank switching. NEW J1 J2 Decoder VDD VCTL VCTL Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

DC Ground 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.
