SKY19003-001

0.6 to 3.0 GHz Dual SPST (2xSPST) Shunt Switch (Two-Bit Control) in a WLCSP Package

The SKY19003-001 is a wafer level chip scale package (WLCSP) dual-shunt, single-pole, single-throw (2xSPST) switch with integrated logic and bias block. Both paths are connected on one side to a single RF ground bump.

The SKY19003-001 linearity is high enough to meet carrier aggregation requirements. The part is designed to sustain a peak voltage of 80 V typical without going to breakdown. The logic block operates with a 1.8 V high control voltage and requires a 2.85 V nominal VDD supply.

The SKY19003-001 is provided in a compact 8-bump, 1.277 x 1.377 x 0.4 mm WLCSP that meets requirements for board-level assembly. Bump diameters are 217 microns, with a minimum bump pitch of 400 microns.

Please note: SKY19003-001 is being discontinued and is not recommended for new designs.
