Bluetooth / Zigbee FEM Quadruples Transmit Range

  • Skyworks’ front end module features RF amplification for operation in a wide variety of temperature
  • Suitable for IoT, IIoT applications and more

Skyworks Solutions, a US-based semiconductor company, introduces the SKY66405-11, which is a high-performance, fully integrated, 2.4 GHz RF front-end module (FEM) designed for Zigbee, Thread, and Bluetooth (including Low Energy) ultra-low power IoT applications spanning sensors, beacons, smart meters and thermostats, wireless cameras, smoke and CO detectors, wearables and medical wearables.

The SKY66405-11 is designed for ease of use and maximum flexibility. The compact (1.9 x 1.9 x 0.56 mm) multi-chip module houses circuitry providing increased efficiency, as well as 4X greater range than stand-alone SoC devices. The module includes a power amplifier, low-noise amplifier, low-loss bypass path, transmit/receive switches, and digital controls compatible with 1.6 V to 3.6 V CMOS levels. The RF blocks operate over a wide supply voltage range from 1.7 V to 3.6 V that allows the SKY66405-11 to be used in battery-powered applications over a wide spectrum of the battery discharge curve.

The integrated LNA enables as much as 6 to 8 dB receive sensitivity improvement versus discrete SoCs and the low power consumption makes it ideal for operation from coin cell batteries. Operating temperature from -40 to 105° C makes the SKY66405-11 suitable for lighting and industrial applications.
