Mingjiada Electronics supplies Qorvo QPF4550SR: 5GHz Wi-Fi 6 RF front-end module (FEM)

Product Description  

The QPF4550SR is a high-performance 5GHz Wi-Fi 6 (802.11ax) RF front-end module (FEM) developed by Qorvo, specifically optimised for applications such as wireless routers, smart home gateways, and IoT devices. The module features a 2.5×2.5mm laminated package (QFN), integrating a power amplifier (PA), low-noise amplifier (LNA), and single-pole double-throw switch (SP2T), providing a complete RF front-end solution that significantly simplifies system design and enhances signal processing efficiency.

Features  

High-performance RF integration

30dB transmit gain, supporting +20.5dBm @ MCS9 VHT80 high linear output power, ensuring high-throughput transmission.  

Ultra-low noise figure (2.1dB), optimising receive sensitivity and enhancing weak signal processing capability.  

13.5dB Rx gain + 8dB bypass loss, supporting flexible signal path switching.  

Wi-Fi 6 Optimised Design

Compliant with the 802.11ax standard, supporting MCS11 HE160 with -43dB dynamic EVM, suitable for high-density network environments.  

30dB 2.4GHz suppression, effectively reducing dual-band coexistence (DBDC) interference.  

Compact packaging and low power consumption  

2.5×2.5mm small-size packaging, saving PCB space, suitable for high-density layouts.

5V single-supply power, operating current as low as 15mA, optimising energy efficiency.  

Enhanced Interference Resistance  

Integrated harmonic filtering (2nd/3rd harmonic suppression) to reduce signal distortion.
