LX5586HLL

RF Front End (LNA + PA) Overview

The LX5586HLL-TR is an RF front-end module designed for 5.15GHz to 5.85GHz frequency bands, supporting 802.11n/ac wireless standards. It features a Single-Pole Double-Throw (SPDT) switch configuration within a compact 16-XFQFN package measuring 2.5mm x 2.5mm. The device operates on a 5V supply and is rated for industrial temperature ranges from -40°C to +85°C. Packaged in tape and reel format with 4500 units per reel, it integrates low-noise amplifier and power amplifier functions for efficient signal transmission and reception.

• Optimized for high-efficiency operation within the 5.15GHz to 5.85GHz Wi-Fi frequency spectrum.
• Compact 16-pin XFQFN footprint enables space-constrained PCB layout designs.
• Robust industrial-grade thermal stability ensures reliable performance across extreme temperature variations.

RF Front End (LNA + PA) Applications

• Wi-Fi routers and access points requiring 802.11n/ac compliance
• Wireless network interface cards (WNICs)
• IoT gateways operating in the 5GHz band

RF Front End (LNA + PA) Procurement Notes

Verify that the ordering suffix matches TR for tape-and-reel packaging. Confirm the manufacturer is Microchip Technology, as Atmel was previously associated with this product line. Ensure the package type is identified as 16-XFQFN or X1QFN with the specified 2.5x2.5mm dimensions. Check for RoHS compliance status if required by specific project regulations.

RF Front End (LNA + PA) Selection Notes

Select this component when designing systems requiring integrated LNA and PA capabilities for 5GHz Wi-Fi applications. The SPDT architecture simplifies board design by reducing external switch requirements. Consider the 5V operating voltage and industrial temperature range (-40°C to +85°C) for environmental suitability. The small form factor is ideal for modern compact wireless devices where board space is limited.
