Skyworks Solutions Inc of Woburn, MA, USA (which manufactures analog and mixed-signal semiconductors) has launched two RF switches suitable for the Internet of Things (IoT) applications including the connected home.
In addition to the connected home, the SKY13587-378LF, which is a gallium arsenide (GaAs) pseudomorphic high-electron-mobility transistor (pHEMT) single-pole dual-throw (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 (SOI) single-pole triple-throw (SP3T) switch made for antenna selection in Wi-Fi applications in IoT systems.
The new switches have an operating temperature range up to 105°C, making them suitable 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, says Skyworks. 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 application board space and design cost for OEMs.?
