Skyworks has introduced two new RF switches for Internet of Things applications. These switches target applications like 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 GHz and 5.8 GHz. The SKY13588-460LF is a CMOS silicon-on-insulator SP3T switch made for antenna selection in Wi-Fi applications in IoT systems.
These advanced switches feature an operating temperature range up to 105°C, making them ideal for applications that require extended temperature operation. 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 20 MHz to 6 GHz (SKY13587-378LF) to 0.1 to 6 GHz (SKY13588-460LF).
These devices are available in compact MLPD/QFN packages (6-or 12-pin), saving board space and lowering the cost for OEMs.
