SE2594L-R

Overview

The SE2594L-R is a dual-band RF front-end module designed for 802.11a/b/g/n WLAN applications, manufactured by Skyworks Solutions Inc. It operates across the 2.4 GHz (2.4–2.5 GHz) and 5 GHz (4.9–5.875 GHz) frequency ranges. The component utilizes Silicon Germanium (SiGe) technology and is housed in a 32-pin QFN package measuring 5x5 mm. It integrates power amplifiers, switches, diplexers, and matching networks to provide a complete solution from transceiver output to antenna.

Feature Summary

• Integrates complete RF front-end functionality including power amplification, switching, and diplexing for dual-band operation.
• Supports multiple IEEE 802.11 standards including a, b, g, and n protocols within a single compact module.
• Utilizes SiGe technology to deliver high performance in a surface-mountable QFN-32 package.

Applications

• Dual-band wireless local area network (WLAN) devices
• Wi-Fi routers and access points supporting 802.11a/b/g/n
• Wireless network equipment requiring integrated RF front-end solutions

Procurement Notes

Verify current availability status as the component may be subject to limited supply or end-of-life conditions. Confirm that the specific ordering suffix matches the required tape-and-reel packaging configuration. Ensure compatibility with existing PCB layout dimensions for the 32-QFN footprint before finalizing procurement decisions.

Selection Notes

Select this component when a unified solution for both 2.4 GHz and 5 GHz bands is required to reduce bill of materials complexity. The integrated nature of the module simplifies design implementation by combining PA, switch, and diplexer functions. Consider the thermal characteristics of the exposed pad QFN package for adequate heat dissipation in dense layouts.
