QPF7219SR

RF Front End (LNA + PA) Overview

The QPF7219SR is a Wi-Fi 6 integrated front end module (iFEM) designed for 2.4 GHz systems. It operates within the 2.402 GHz to 2.472 GHz frequency range and utilizes a 5 V supply voltage. The device integrates a power amplifier, BAW filter, SP2T switch, and low noise amplifier in an LGA-24 package. Key electrical parameters include a transmit gain of 31 dB, receive gain of 15.5 dB, and a noise figure of 2 dB. The component supports SMD/SMT installation and features humidity sensitivity.

RF Front End (LNA + PA) Feature Summary

• Integrates active components with BAW filter technology for compact layout and reduced external component count
• Optimized for 5 V operation to save power while maintaining linear output across all channels
• Includes integrated chip-level filtering for second and third harmonics and 5 GHz suppression for DBDC operations
• Features a bypassable low noise amplifier and allows external filtering placement on the receive path

RF Front End (LNA + PA) Applications

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

RF Front End (LNA + PA) Procurement Notes

Verify current availability status as the QPF7219SR has been marked as End-of-Life (EOL). Confirm RoHS compliance details through official documentation before procurement. Ensure handling procedures account for moisture sensitivity classification during storage and reflow processes. Validate that the LGA-24 package matches the target PCB footprint requirements.

RF Front End (LNA + PA) Selection Notes

Select this iFEM for designs requiring high integration and optimized performance at 5 V. Consider the specific need for FCC band-edge compliance and dynamic EVM performance in Wi-Fi 6 applications. Evaluate the trade-off between the integrated solution's size benefits and the requirement for potential external filtering on the Rx path.
