DATA SHEET SKY13296-340LF: GaAs SP4T Absorptive Switch 20 MHz2.5 GHz Functional Diagram Features RFc Positive voltage control (0/3 V to 0/5 V) High isolation 35 dB at 1 GHz J J 4 1 Integrated silicon CMOS driver Isolated ports are absorptive Use of external DC blocks to allow good return loss to low frequency External External Floating Caps Floating Caps Available lead (Pb)-free and RoHS-compliant MSL-1 260 C per JEDEC J-STD-020 J J 3 2 Description The SKY13296-340LF is a pHEMT GaAs FET IC high isolation, absorptive single-pole four-throw switch packaged in a lead Decoder (Pb)-free, 4 x 4 mm, 20-lead exposed-pad plastic package for low-cost commercial applications. The use of external DC V V V DD CTL CTL 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 Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
