Empowering Wi-SUN® Applications with Skyworks’ SKY66122-11



Designed to optimize connectivity in Wireless Smart Ubiquitous Network (Wi-SUN®) applications, Skyworks’ SKY66122 is a front-end module (FEM) that seamlessly collaborates with System on Chip (SoC) radio transceivers like the Silicon Labs EFR32FG25 or EFR32FG28.


The SKY66122 amplifies the performance of smart metering, smart lighting, and various IoT devices. It significantly enhances overall efficiency and boosts link budgets by integrating next-generation components like high linear transmit output power amplifiers (PA), low noise amplifiers (LNA), switches, harmonic filters, and matching networks.


The versatility of the SKY66122-11 is underscored by a wide voltage supply range and ultra-low sleep mode current. It’s an ideal solution for battery-powered devices, standby equipment, and more.
