The SKY66405-11 is a high-performance, fully integrated RF
front-end module (FEM) designed for Zigbee, Thread, and
Bluetooth (including Low Energy) applications.
The SKY66405-11 is designed for ease of use and maximum
flexibility. The device provides a power amplifier, low-noise
amplifier, low-loss bypass path, transmit/receive switches, and
digital controls compatible with 1.6 V to 3.6 V CMOS levels.
The RF blocks operate over a wide supply voltage range from
1.7 V to 3.6 V that allows the SKY66405-11 to be used in battery
powered applications over a wide spectrum of the battery
A functional block diagram is shown in Figure 1. The
SKY66405-11 is provided in a small 1.9 mm x 1.9 mm x 0.56 mm
Multi-Chip Module (MCM) package.
