SKY66110-11 BLUETOOTH® Low Energy Front-End Module Skyworks Solutions, Inc. SKY66110-11 BLUETOOTH® Low Energy (BLE) Front-end Module (FEM) features a transmit section that draws 10mA at 10dBm output power in the 2.4GHz frequency range. Low current draw is critical in products using coin cell batteries such as wearables, hearing aids, sensors, and more. Although some transceiver chips have on-board Tx power amplifiers, the addition of the Skyworks BLE FEM can more than double the effective range of some SoCs. Due to the higher efficiency of a dedicated PA, overall system current usage can be decreased by up to 30% while providing the same output power as the stand-alone SoC. Offered in a 3mm x 3.3mm package, the SKY66110-11 from Skyworks potentially eliminates antenna matching networks and thereby reduces overall circuit size for space-limited applications.
