EFF01 RF Front End Modules

Coming Soon

The EFF01 Front End Module (FEM) is a highly integrated Sub-GHz FEM designed to maximize the range of Sub-GHz networks. It is the first Sub-GHZ FEM with integrated power amplifier and low noise amplifier to enable a maximum power output of +30dBm. When used with our EFR32FG25 devices, the EFF01 can also provide closed loop power control to minimize variation in transmit power and BOM optimization in a small form factor 4x4 QFN package.
