QPF4588SR

RF Front End (LNA + PA) Overview

The Qorvo QPF4588SR is an integrated front-end module (FEM) designed for Wi-Fi 6 (802.11ax) systems operating in the 5 GHz band. It integrates a power amplifier, SP2T switch, bypassable LNA, and coupler into a compact 5.0 x 3.0 mm QFN package. Optimized for 5 V operation, it delivers 33 dB transmit gain and 16 dB receive gain with a 2 dB noise figure. Key specifications include a minimum frequency of 4.900 GHz, maximum frequency of 5.925 GHz, OP1dB of 32 dBm, and receive current of 20 mA.

RF Front End (LNA + PA) Feature Summary

• Integrates PA, SP2T switch, bypassable LNA, and coupler to minimize layout area
• Optimized for 5 V power supply to maintain high linear output power and efficiency
• Provides consistent noise coefficient performance across wide conditions to maximize Rx sensitivity
• Includes integrated chip-level filtering for 2nd and 3rd harmonics and 2.4 GHz suppression

RF Front End (LNA + PA) Applications

• Wi-Fi 6 access points
• Wireless routers
• Client equipment
• Customer premises equipment

RF Front End (LNA + PA) Procurement Notes

Verify the specific suffix 'SR' against the manufacturer's official documentation to confirm package type and tape/reel configuration. Ensure the component matches the required 5.0 x 3.0 mm QFN footprint. Cross-reference the datasheet revision date to confirm compliance with current Wi-Fi 6 standards. Confirm that the integrated matching circuits are suitable for the target PCB design without additional external components.

RF Front End (LNA + PA) Selection Notes

Select this FEM for designs requiring a compact solution for 5 GHz Wi-Fi 6 applications. The integrated matching reduces board space compared to discrete solutions. Consider the 5 V voltage requirement for power management. Evaluate the need for external filtering if the application demands stricter spectral masks than the integrated harmonic filters provide. Check compatibility with existing antenna switching architectures.

RF Front End (LNA + PA) Part Context

The QPF4588SR belongs to Qorvo's integrated front-end module family targeting wireless connectivity. It complements other modules like the QPF4219 for 2.4 GHz bands. The SR suffix typically denotes a specific reel or packaging variant within the standard QPF4588 product line. This series supports the evolution from Wi-Fi 5 to Wi-Fi 6 standards by offering improved linearity and efficiency.
