RFFM6909 RFFM6909 925MHz Transmit/Receive Module This module is intended for 868MHz and 915MHz AMR solutions. The FEM provides separate ports for Rx/Tx paths, single-ended Tx and single-ended Rx or Rx differential port, 14dB gain single stage LNA, and single port antenna connection. The PA switch provides a nominal insertion loss of 0.8dB. The device is provided in a 4.0mm x 3.0mm, 18-pin package.
