AMI/AMR smart energy transmit/receive front end modules

May 28, 2012 // By Jean-Pierre Joosting
The RF65x9 series of transmit/receive modules from RFMD integrate a complete solution in a single front-end module (FEM) for AMI/AMR and Smart Grid solutions. The FEMs integrate a PA, transmit (Tx) filtering, input and output switches, a Tx or receive (Rx) attenuation path, and an LNA with bypass mode.

Single-ended input and output are included for optimized ease of use and implementation. The pin-out of the FEM enables users to implement additional filtering external to the module, if needed.

For the RF6509, RF6519 and RF6569 respectively, output power is 29.5 dBm, 26 dBm and 30 dBm; while transmit gain is 31 dB, 30 dB and 15 dB. For the RF6509 and RF6519 respectively, receive gain is 18 dB and 17 dB, while noise figure is 2.5 dB and 1.5 dB.

Typical applications include 868MHz/900MHz ISM band applications, single chip RF front end modules, portable battery powered equipment, and wireless automatic metering.
