SKY66405-11 Block Diagram No external bias resistor is required Small MCM (1.9 mm x 1.9 mm x 0.56 mm) package, NiPdAu- Description plated (MSL3, 260 C per JEDEC-J-STD-020) 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 discharge curve. 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. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 2.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. 2 CW test signal. ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. Skyworks Solutions, Inc.
