5.3.2: Reference Front End Module
The Front End Module (FEM) contains the HPA, LNA and duplexer needed to use the BRM as a
terminal.
The FEM is supplied as an example reference design configured for BGAN Class 2 operation but
capable of meeting the RF performance requirements for all BGAN land and maritime classes. Some
further development work is typically required to adapt the reference design for use within a specific
production ready terminal design.
Note:
If you need to upgrade the Firmware for the FEM, please refer to
