QPF4591
Wi-Fi 6 Dual Path Front End Module
®
Product Overview
The Qorvo® QPF4591 is an integrated dual path front end
module (FEM) designed for Wi-Fi 6 (802.11ax) systems which
allows 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.
Receive path matches the optimal
technologies to maximize Rx sensitivity through noise figure
performance that is consistent over a wider variety of conditions
while maintaining low current draw.
