SKY19245-686LF中文资料Antenna Tuning Switches数据手册Skyworks规格书

描述 Description

The SKY19245-686LF is a Quad Flat No-Lead (QFN) single-pole,four-throw (SP4T) switch designed for antenna tuning applicationsthat require very low RON and COFF. Switching is controlled by anintegrated GPIO interface with three control pins. Depending onthe logic voltage level applied to the control pins, the antenna portcan be either connected to one of the four switched RF outputs orto multiple pre-defined outputs simultaneously, while the other RFports are in isolation state to antenna port.

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

The SKY19245-686LF is provided in a compact 10-pin,1.5 x 1.1 x 0.5 mm maximum QFN that meets requirements forboard-level assembly.
