QPF4532SR

RF Front End (LNA + PA) Overview

The QPF4532SR is a Wi-Fi 6 (802.11ax) integrated front-end module designed for 5 GHz applications. It operates within the 5.15 GHz to 5.895 GHz frequency range and utilizes a 3.3 V supply voltage. The device integrates a power amplifier, SP2T switch, and bypassable low-noise amplifier in a compact 16-QFN package measuring 2.5 mm x 2.5 mm. Key electrical parameters include a transmit gain of 31 dB, receive gain of 13.5 dB, and a noise figure of 2.1 dB. Output power reaches 21 dBm under 11ac conditions with an EVM of -35 dB.

RF Front End (LNA + PA) Procurement Notes

Verify the specific suffix 'SR' against official Qorvo documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with IEEE 802.11ax standards and required 3.3 V operating voltage. Cross-reference pinout and thermal pad requirements with the latest datasheet to prevent integration errors during PCB layout.

RF Front End (LNA + PA) Selection Notes

Select this module for applications requiring high linearity and spectral compliance in Wi-Fi 6 environments. The integrated harmonic filtering reduces external component count. Consider the 2.5 mm x 2.5 mm footprint for space-constrained designs. Verify that the 2.4 GHz rejection meets system isolation requirements for concurrent dual-band operation.
