2.4 GHz ZigBee®/Smart Energy Front-End Module: SKY66109-11


The SKY66109-11 is a front-end module with quite a few components integrated into it. These include a power amplifier with up to +22.5 dBm output power, and low noise amplifier with programmable bypass, and an antenna switching with transmit and receive diversity function.

This FEM is ideal for applications involving smart meters, in-home appliances, and smart thermostats. It features a 2dB (typical) noise figure, a differential transmit/receive interface with integrated baluns, <800 ns switch on/off time, a 2.0 to 3.6 V supply range, and a 0.05µA (typical) sleep mode current. It comes in a 20-pin, 3 x4 x 0.9mm package, and the front-end module requires no bias resistor.
