The SKY66118-11 is a high-performance, fully integrated RF front-end module (FEM) designed for Bluetooth, Zigbee, and Thread applications. The device integrates a 20 dBm power amplifier, RF switches, output matching, and harmonic filtering. The FEM supports three modes of operation (transmit mode, bypass mode, and an ALL OFF sleep mode), using simple 2-pin GPIO control. The low transmit current consumption and operation over a wide supply range enable the FEM to be used with a direct battery connection, supporting a wide range of battery discharge voltages. The output power can also be externally adjusted through the VCTRL pin. It is available in a 2.6 x 2.4 x 0.75 mm Multi-Chip Module (MCM) package and is ideal for wearables, smart lighting, and IoT devices.
