Shenzhen Mingjiada Electronics Co., Ltd. is currently offering a long-term supply of Qorvo QPF4550 series RF front-end modules (FEMs) to customers worldwide. At the same time, we are seeking to purchase original QPF4550 stock at competitive prices, providing a one-stop service comprising the supply of original stock and professional stock acquisition. The QPF4550 is a high-performance 5GHz integrated front-end module (FEM) designed by Qorvo specifically for Wi-Fi 6 (802.11ax) systems. It is widely used in wireless routers, smart home gateways, Internet of Things (IoT) devices, and enterprise-grade wireless network infrastructure.
I. Qorvo QPF4550 Product Overview
The Qorvo QPF4550 is an integrated 5GHz radio frequency front-end module (FEM) designed specifically for Wi-Fi 6 (802.11ax) systems. The module integrates a 5GHz power amplifier (PA), a single-pole double-throw (SP2T) switch and a bypassable low-noise amplifier (LNA) within a single device, providing a complete radio frequency front-end solution.
The QPF4550 utilises a compact 2.5 mm × 2.5 mm laminated package (QFN-16). Its small form factor and integrated matching functionality minimise the PCB layout area required in applications, making it ideal for modern wireless communication devices with stringent space constraints.
