Skyworks has introduced the SKY66121-11, a high efficiency, high performance transmit/receive front-end module (FEM) that provides greater than four times range extension. The device features low power consumption and enables fast switch timing in a compact 16-pin, 4 x 4 mm package that enables low-cost manufacturing.
The front-end module includes a power amplifier capable of more than +30 dBm of transmit output power. All functionality can be controlled by a two-wire interface. The FEM can be placed in a deep “sleep” mode, drawing less than 1 μA of current.
The receive chain consists of a low-loss single-pole, double-throw (SPDT) switch. Three separate VCC pins enable maximum RF isolation.
The SKY66121-11 is ideal for IoT applications including smart metering, connected home, smart city sensors, and industrial, scientific and medical (ISM).
