Two RF switches ideal for IoT applications, including the connected home, have been introduced by Skyworks. In addition to the connected home, the SKY13587-378LF, which is a pHEMT GaAs SPDT switch, can be used for transmit and receive switching in industrial, lighting and smart energy applications, as well as 802.11a/b/g/n WLAN networks that operate at 2.4 and 5.8 GHz. 

The SKY13588-460LF is a CMOS silicon-on-insulator SP3T switch made for antenna selection in WiFi applications in IoT systems.

These advanced switches feature an operating temperature range up to 105°C, making them suited for applications that require extended temperature. They also boast high isolation and low insertion loss which is best for low-power transmit/receive applications. Their positive voltage control provides low current and optimal efficiency for battery-operated IoT applications and their broadband frequency ranges from 20Mhz to 6.0GHz (SKY13587-378LF) to 0.1 to 6.0GHz (SKY13588-460LF).

These devices are available in compact MLPD/QFN packages (6- or 12-pin), saving precious application board space and design cost for OEMs.
