High Isolation, Broadband RF Switches

Skyworks introduces its high isolation, broadband RF switches for Internet of Things (IoT) applications

Image of Skyworks' High Isolation, Broadband RF SwitchesSkyworks offers a family of high isolation (47 dB) multi-throw switches for 0.7 GHz to 3 GHz Rx switching. The SKY13522-644LF, SKY13523-639LF, and SKY13524-639LF are designed for switching single-ended Rx SAW filters in cellular handsets. Consuming less than 10 µA of current, they are ideal for low power switching in smartphone, data card, IoT, infrastructure, and test and measurement applications and may be used for switching filter banks in infrastructure Rx chains. The small footprint devices are supplied in quad-flat no-lead (QFN) packages: 14-pin, 1.6 mm x 1.6 mm x 0.45 mm (-639LF) and 8-pin, 1.1 mm x 1.1 mm x 0.45 mm (-644LF).
