RFMD’s AMI/AMR Smart Energy Tx/Rx Front End Modules consists of three separate models ideal for wireless automatic metering, single chip RF front end module, portable battery powered equipment, and 868MHz/900MHz ISM band applications.
This front end module (FEM) features an ultra-small form factor and is ideal for IEEE802.11a/n/ac WiFi applications, 4.9GHz to 5.85GHz ISM Band applications, applications involving portable battery powered equipment, and applications involving WiFi access points, gateways, and set top boxes.
The RF5725 is a single-chip integrated front-end module (FEM) for high performance WLAN applications in the 2.4GHz to 2.5GHz ISM band. This FEM greatly reduces the number of external components, minimizing footprint and assembly cost of the overall 802.11b/g solution. The RF5725 has an integrated b/g power amplifier, LNA, a Coupler Power detector, and TX filtering. It also is capable of switching between WLAN RX, WLAN TX, and BTH RX/TX operations. This device is manufactured using GaAs HBT and pHEMT processes on a 3mmx3mmx0.5mm 16-pin QFN package. This module meets or exceeds the RF front-end needs of 802.11b/g WLAN RF systems.
