RF Micro Devices, Inc. (RFMD) announced the availability of the RFFM6903 front end module (FEM). RFMD's highly-integrated RFFM6903 FEM meets or exceeds the system requirements for AMI/AMR smart meter applications operating in the 868MHz – 960MHz frequency band. The FEM supports multiple applications, including Smart Energy/advanced metering infrastructure (AMI), portable battery-powered equipment, and general 868/915MHz ISM band systems.
The feature-rich RFFM6903 integrates a +30.5dBm power amplifier (PA) with a Tx harmonic output filter in the transmit path, a Tx path bypass mode with harmonic filter, and a low-noise amplifier (LNA) with bypass mode in the receive path and is packaged in a 6mm × 6mm × 1mm laminate package. The RFMD® RFFM6903 also includes a low insertion loss, high isolation, single-pole three-throw (SP3T) switch and separate Rx/Tx 50 ohm ports that simplify matching and provide input and output signals for both the Tx and Rx paths. In the receive path, the Rx chain provides 16dB of typical gain with only 5mA of current and an excellent noise figure of 1.7dB.
Availability
The RFFM6903 is available for sampling and mass production.
