Description

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  1.1  0.5 mm maximum QFN that meets requirements for

board-level assembly.

A functional block diagram is shown in Figure 1.
