0.7 to 2.7 GHz Triple SPST (3xSPST) Shunt MIPI® Antenna Tuning Switch

The SKY19237-001 is a wafer level chip scale package (WLCSP) triple-shunt, single-pole, single-throw (3xSPST) switch with integrated logic and bias block. The three paths are connected on one side to a single RF ground bump.

The part is designed to sustain a peak voltage of 83 V typical without going to breakdown.

The switching is controlled by an integrated Mobile Industry Processor Interface (MIPI) decoder.

The SKY19237-001 is provided in a compact 11-bump, 1.66 × 1.75 × 0.5 mm (typical) WLCSP that meets requirements for board-level assembly. Bump diameters are 262 m, with a minimum bump pitch of 400 m.
