RF switches for connected home wireless networks

Jon Lawson

Skyworks has launched two RF switches for the Internet of Things (IoT) applications including the connected home.

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 2.4GHz and 5.8GHz. The SKY13588-460LF is a CMOS silicon-on-insulator SP3T switch made for antenna selection in Wi-Fi applications in IoT systems.

The switches feature an operating temperature range up to 105°C for applications that require extended temperature. They also provide high isolation and low insertion loss for low-power transmit/receive applications. The positive voltage control provides low current and optimal efficiency for battery-operated IoT applications and their broadband frequency ranges from 20 MHz to 6.0GHz for the SKY13587-378LF to 0.1 to 6.0GHz for the SKY13588-460LF.

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