Qorvo QPF4219 front-end module for Wi-Fi 5 designs
The QPF4219 front-end module (FEM) from Qorvo is designed for Internet of Things (IoT) systems based on Wi-Fi 5 (802.11ac). The 2.4 GHz FEM offers a compact form factor and integrated matching to minimise layout area in applications such as wireless routers, residential gateways and access points.
The FEM integrates a 2.4 GHz power amplifier (PA), regulator, single-pole double-throw (SPDT) switch, low-noise amplifier (LNA) with bypass mode and voltage power detector into a single device. The device focuses performance on optimising the PA for a 5 V supply voltage by conserving power consumption while maintaining high linear output power and good throughput.
The product maximises receive (Rx) sensitivity through a 1.9 dB noise figure performance that is consistent over a variety of conditions. It also includes integrated die-level filtering for second and third harmonics as well as 5 GHz rejection for dual-band dual-concurrent (DBDC) operation.
