描述 Description

The SKY19244-686LF is a Quad Flat No-Lead (QFN) single-pole,triple-throw (SP3T) switch designed for antenna tuningapplications that require very low RON and COFF. Switching iscontrolled by an integrated GPIO interface with three control pins.Depending on the logic voltage level applied to the control pins,the antenna port can be either connected to one of the threeswitched RF outputs or to multiple pre-defined outputssimultaneously, while the other RF ports are in isolation state toantenna port.

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

The SKY19244-686LF is provided in a compact 10-pin,1.5 x 1.1 x 0.5 mm maximum QFN that meets requirements forboard-level assembly.
