QPF4200SR

RF Front End (LNA + PA) Overview

The QPF4200SR is an integrated front-end module (FEM) designed for Wi-Fi 6 (802.11ax) systems operating in the 2.4 GHz band (2412 MHz to 2484 MHz). It integrates a power amplifier, regulator, SP2T switch, bypassable low noise amplifier, and DC power detector. The device features a 16-QFN exposed pad package with integrated matching circuitry to minimize layout area.

RF Front End (LNA + PA) Feature Summary

• Integrates a 2.4 GHz power amplifier, regulator, single pole two throw switch, bypassable low noise amplifier, and DC power detector within a single component.

RF Front End (LNA + PA) Applications

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

RF Front End (LNA + PA) Procurement Notes

Verify current availability status as the QPF4200SR is listed as End of Life on distributor platforms. Confirm final order quantities against manufacturer discontinuation notifications prior to procurement. Ensure compatibility with existing design-in requirements given the obsolescence schedule.

RF Front End (LNA + PA) Selection Notes

Select this component for compact 2.4 GHz Wi-Fi 6 designs requiring integrated RF switching and amplification. Evaluate the 16-QFN package constraints and thermal dissipation needs. Consider the integrated regulator and DC power detection capabilities for simplified biasing and monitoring architectures.

RF Front End (LNA + PA) Part Context

The QPF4200SR belongs to Qorvo’s QPF series of front-end modules optimized for wireless connectivity. It complements other variants like the QPF4219 and QPF4230 by providing specific integration for 2.4 GHz Wi-Fi 6 applications with reduced board space requirements through internal matching networks.

RF Front End (LNA + PA) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End of Life status, alternative sourcing or redesign may be necessary.
