Description For additional information, refer to Skyworks The SKY19245-686LF is a Quad Flat No-Lead (QFN) single-pole, TM Denition of Green , document number four-throw (SP4T) switch designed for antenna tuning applications SQ040074. 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 0.45 mm typical QFN that meets requirements for board-level assembly. A functional block diagram is shown in Figure 1.
