Multi-protocol front-end module extends range in compact form factor

For low power IoT applications, Skyworks’ SKY66405-11 front-end module is designed for Zigbee, Thread and Bluetooth.

The 2.4GHz front-end module can be used in a range of applications from sensors, beacons, smart meters and thermostats to wireless cameras, smoke and CO detectors, consumer wearables and medical wearables.

The integrated multi-chip module (MCM) is supplied in a compact form factor (1.9 x 1.9 x 0.56mm) and provides increased efficiency as well as more than four times the range when compared with system-on-chip (SoC) alone, says Skyworks.

The module includes a power amplifier, low-noise amplifier, low-loss bypass path, transmit and receive switches and digital controls compatible with 1.6 to 3.6V CMOS levels. Its wide supply voltage range also allows the device to be used in battery powered IoT applications over a broad spectrum of the battery discharge curve. It also covers worldwide unlicensed bands.

The operating temperature ranges from -40 to +105 degrees C, suitable for lighting and industrial applications.

The SKY66405-11 has an integrated power amplifier (+13dBm output power), integrated low noise amplifier (LNA) with a typical noise figure of 2dB. Other features are a single-ended transmit/receive interface, fast switch on/off time and no external bias resistor is required.

Skyworks Solutions supplies analogue semiconductors for use in the aerospace, automotive, broadband, cellular infrastructure, connected home, industrial, medical, military, smartphone, tablet and wearable markets. Skyworks has engineering, marketing, operations, sales and support facilities located throughout Asia, Europe and North America.
