The RF6559 from RFMD is a front end module (FEM) for 915-MHz AMR systems. It contains an integrated three-stage PA with 42 dB of gain and typical power output of 28 dBm. The module allows for Tx/Rx on a single antenna via 2 integrated SPDT switches.

Tx filtering, built-in Power Detector, and a two-stage LNA with typical gain of 32 dB are also included, packaged in a 28-pin, 6-mm x 6-mm laminate package with backside ground.

Typical applications include wireless automated metering, wireless alarm systems, portable battery powered equipment, smart energy, 868MHz/915MHz ISM band, and single-chip RF front end modules.
