Overview: Product Overview
The Qorvo® RFFM4558A is an integrated front end module (FEM) designed for Wi-Fi 802.11ac systems. The compact form factor and integrated matching minimizes layout area in the application. Performance is focused on optimizing the power amplifer for a 5V supply voltage that conserves power consumption while maintaining the highest linear output power and leading edge throughput. Receive path matches the optimal technologies to maximize Rx sensitivity through noise figure performance that is consistent over a wider variety of conditions. Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included. A DC power detector which has voltage output is integrated as a power control feedback option. The RFFM4558A integrates a 5 GHz power amplifier (PA), regulator, single pole two throw switch (SP2T), and bypassable low noise amplifier (LNA) into a single device
