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

The SKY59256-701LF 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 SKY59256-701LF 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.
