Front-end module well suited for smart energy & advanced metering Infrastructure applications

Targeting Smart Energy/AMI applications operating in the 405MHz-475MHz frequency range, as well as for portable battery powered equipment and general 433/470MHz ISM band systems, the highly-integrated RFFM6403 front end module (FEM) from RF Micro Devices (RFMD) integrates a transmit high power path with a +30.5dBm PA and Tx harmonic output filtering, a transmit bypass thru path with Tx harmonic output filtering, and a receive path with a low noise amplifier (LNA) with bypass mode. The FEM also features a low insertion loss/high isolation SP3T switch and separate Rx/Tx 50? ports, simplifying matching and providing input and output signals for both the Tx and Rx paths. The RFFM6403 is designed for AMI systems operating with high efficiency requirements and a minimum output power of 30 dBm. In the receive path, the Rx chain provides 16 dB of typical gain with only 5 mA of current and an excellent noise figure of 1.7 dB. The high level of integration and industry-leading form factor (6mm x 6mm x 1mm) minimize product footprint at the customer device while reducing external component count and associated assembly costs.
