RFFM6401

3.3V to 4.0V, 450MHz to 470MHz

Transmit/Receive Front End Module

RFFM6401 is a front end module (FEM) intended for 433MHz to 470MHz AMI/AMR

systems. This module provides separate ports for Rx and Tx paths. The Tx section

provides a two stage PA with nominal output power of 30dBm and gain of 30dB.

The Rx is a pass through. Both are combined to a single antenna port with a SP2T

switch. The device is provided in a 5.5mm x 5.0mm, 28-pin package.
