SKY13373-460LF

The SKY13373-460LF is a Skyworks silicon-on-insulator single-pole triple-throw RF switch that covers a very wide frequency range, from 100 MHz to 8 GHz, in a compact 2 by 2 millimetre QFN package. It is designed to route a radio signal among three paths, such as three antennas or three bands, with low insertion loss of about 0.45 dB at 2.5 GHz and high isolation of about 30 dB, so it preserves the link budget while keeping the unused paths well separated. The SOI process gives fast switching and low control current, and the part uses standard logic control, so it interfaces directly to a radio or baseband controller. Because it spans such a wide frequency range, the same switch can serve Wi-Fi, cellular and infrastructure designs, which simplifies sourcing across a product family. It is commonly paired with a front-end module or an LNA to complete a transmit/receive or multi-antenna front end. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports control timing, layout and isolation verification.
