Skyworks introduces two front-end modules 

Two modules from Skyworks, the SKY66118-11 and the SKY66407-11, are 2.4GHz front-end modules for Bluetooth internet of things (IoT) applications. They can be used for smart watches, trackers, connected home systems, wireless and gaming headsets.

The low power modules are claimed to significantly improve range (by more than a factor of two) compared to standalone system-on-chip (SoC) implementations. It efficiently delivers more power to the antenna, minimising or potentially eliminating any required antenna matching network. The modules also integrate power amplifier output matching, harmonic filtering, and bypass path switching which enable flexible and innovative end product designs for space-constrained IoT applications.

The SKY66118-11 (pictured) is a fully integrated RF front-end module designed for Bluetooth, Zigbee, and Thread applications. It is designed for ease of use and maximum flexibility. The device integrates a +20 dBm power amplifier, RF switches, output matching and harmonic filtering. Using simple two-pin general purpose input/output (GPIO), the module supports three modes of operation (transmit mode, bypass mode, and an all-off sleep mode). The output power can also be externally adjusted through the VCTRL pin.

The low transmit current consumption and operation over a wide supply range enables the module to be used with a direct battery connection, supporting a wide range of battery discharge voltages, says Skyworks.

Output power control is ±1dB and the supply range is 1.7 to 3.3V. Operating temperature range is -40 to +105 degrees C.

The SKY66118-11 is a small 18-pin MCM (2.6 x 2.4 x 0.75mm) package.

The second module is the SKY66407-11 front-end module designed for Bluetooth IoT applications operating in the 2.4 to 2.4835GHz range. The device is provided in a 1.2 x 1.2 x 0.35mm nine-pin CSP.

It has a wide supply range of 1.7 to 3.6 V, with ESD rating of 2kV. It has a low sleep current of less than one microA and is available in a nine-pin CSP rated to  MSL1, 260 degrees C per JEDEC-J-STD-020.
