Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the QPF4219 front end module (FEM) from Qorvo. 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 minimize layout area in applications such as wireless routers, residential gateways, and access points.
Qorvo’s QPF4219 FEM, available from Mouser Electronics, 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 optimizing the PA for a 5V supply voltage by conserving power consumption while maintaining the highest linear output power and exceptional throughput. The QPF4219 maximizes receive (Rx) sensitivity through a 1.9 dB noise figure performance that is consistent over a variety of conditions. The device also includes integrated die-level filtering for second and third harmonics as well as 5 GHz rejection for dual-band dual-concurrent (DBDC) operation.
