The SKY85728-11EK1 is a highly integrated front-end module (FEM) designed for 2.4 GHz WLAN applications. This FEM is part of Skyworks Solutions Inc.'s extensive portfolio of wireless connectivity solutions, catering to the demands of modern, high-performance Wi-Fi systems. It integrates a power amplifier (PA), a low-noise amplifier (LNA) with bypass, and a transmit/receive (T/R) switch into a single compact package, simplifying the design and reducing the footprint on the printed circuit board (PCB).

Applications:

• Wi-Fi routers and access points: Used in home and enterprise networking equipment to improve signal strength and range.
• IoT devices: Integrated into various Internet of Things (IoT) devices requiring reliable 2.4 GHz WLAN connectivity.
• Wireless repeaters and extenders: Employed to boost and extend the coverage of existing Wi-Fi networks.
• Smart home hubs: Incorporated in smart home controllers to manage and connect various smart devices.
• Mobile devices: Although less common due to the trend towards 5 GHz, it can be found in some legacy or cost-sensitive mobile applications.

Features:

• Integrated PA, LNA, and T/R switch: Reduces external component count and simplifies board layout.
• High transmit power: Enables extended range and improved signal strength.
• Low noise figure: Enhances receiver sensitivity and improves data throughput.
