Qorvo Launches Compact Front End Module to Power the Next Generation of Wi-Fi 7 Devices

Qorvo has introduced the QPF4509, a compact and highly integrated front end module (FEM) designed specifically for Wi-Fi 7 (802.11be) systems. This latest product is engineered to meet the growing demands of next-generation wireless networking, offering powerful performance, efficiency, and a smaller footprint for space-constrained designs.

The QPF4509 delivers exceptional output power and linearity across the full 5 GHz band (UNII1-4), supporting peak performance for access points, wireless routers, set-top boxes, and a wide range of smart home and IoT devices. Its design emphasizes low power consumption by optimizing performance for a 5V supply, which also supports systems using digital pre-distortion (DPD) to push linear output and throughput to new levels.

Inside the QPF4509 is an integrated 6 GHz power amplifier, a single-pole double-throw (SP2T) switch, a bypassable low-noise amplifier, and a built-in RF coupler for feedback training. A DC logarithmic power detector ensures accurate power control and feedback, all within a single, streamlined device.

From a performance perspective, the module supports output powers such as +12 dBm at MCS13 EHT160 with -47 dB dynamic EVM, +20.5 dBm at MCS11, and up to +26 dBm for MCS0 HT20, all while maintaining compliance with spectral masks. With 29 dB transmit gain, 1.8 dB noise figure, and 15 dB receive gain, it delivers robust and reliable performance for high-throughput connectivity.

The QPF4509 is ideally suited for consumer and enterprise networking products, including distributed Wi-Fi systems, smart home gateways, and other customer premise equipment. It integrates easily into system designs, reducing development time and board complexity while ensuring compatibility with advanced wireless standards.
