SKY19244-686LF

0.1 to 2.7 GHz SP3T High-Power Antenna Tuning Switch in a QFN Package


Please note: SKY19244-686LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY19245-686LF



The SKY19244-686LF is a Quad Flat No-Lead (QFN) single-pole, triple-throw (SP3T) switch designed for antenna tuning applications that require very low RON and COFF. Switching is controlled 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 three switched RF outputs or to multiple pre-defined outputs simultaneously, while the other RF ports are in isolation state to antenna port.

No external DC blocking capacitors are required as long as no DC voltage 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 for board-level assembly.
