0.6 to 6.0 GHz 4xSPST Shunt MIPI Antenna Tuning Switch in a QFN Package

The SKY19256-701LF is a Quad Flat No-Lead (QFN) 4X singlepole, single-throw (4xSPST) switch designed for antenna tuning applications that require ultra-low ON resistance and low OFF capacitance. Switching is controlled by an integrated Mobile Industry Processor Interface (MIPI) controller.

No external DC blocking capacitors are required as long as no DC voltage is applied on any RF path.

The SKY19256-701LF is provided in a compact 10-pin, 1.5 x 1.1 x 0.45 mm (typical) QFN that meets requirements for board-level assembly.
