Qorvo QPF4591 5.0GHz Wi-Fi® 6 Dual-Path Front End Module (FEM) features a 5.150GHz to 5.925GHz frequency range, up to 30dB transmit gain, and a low 2.8dB noise figure. Found at Mouser, the QPF4291 is designed for IEEE 802.11ax systems which allow the operation of two separate RF chains to flow through a single Front End Module. The compact form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. Performance is focused on optimizing a multi-mode PA for a 3.85V supply voltage that allows for optimal throughput based on user conditions. The receive path matches the optimal technologies to maximize Rx sensitivity through noise figure performance consistent over a wider variety of conditions while maintaining a low current draw.
