Description

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.

A functional block diagram is shown in Figure 1.
