描述 Description

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.
The QPF4591 dual path front end module features chipset-specific compatible control voltages to facilitate ease of use.
The QPF4591 integrates multiple 5 GHz power amplifiers (PA) with power detector, transmit-receive switches and bypassable low noise amplifiers (LNA) into a single device.
