Description
The SKY19245-686LF is a Quad Flat No-Lead (QFN) single-pole,
four-throw (SP4T) 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 four 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 SKY19245-686LF 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.
