RFMD is shipping in volume, the RF5924, said to be the industry's first front-end module (FEM) designed specifically for embedded wireless LAN (WLAN) applications in cellular handsets.
The RF5924 is a complete front-end module that requires no external components, enabling the smallest footprint area of any 802.11g front-end module on the market today, according to the company. Featuring a WLAN power amplifier, switch and receive balun, the chip provides all the required functions between the RF transceiver and the system BPF/antenna. With all RF ports 50 Ω matched, the RF5924 IC is designed to ease system implementation and reduce product development time.
Key features of the RF5924 include: 3,5 x 3,5 x 1,4 mm module; POUT =16 dBm, 11 g, OFDM<3,3% EVM; direct battery connection (single 3,1 to 4,5 V supply); integrated 2,5 GHz b/g amplifier, RX balun and switch; Bluetooth port-shared antenna between WLAN and Bluetooth systems.
