Targeted at embedded applications including cellular handsets, gaming, digital cameras and personal media players (PMP), the SE2571U front-end module works directly from battery and integrates four key front-end components into a 3 x 3 x 0.5-mm MSL 1 package. The part provides a complete 2.4-GHz WLAN RF transmitter and Bluetooth receiver solution from the output of the transceiver to the antennas and from the antennas to the input of the transceiver.
In addition, the device delivers 20 dBm in 802.11b mode and a full 19-dBm linear power in 802.11g mode and can operate from 2.7 to 4.8 V for direct-to-battery applications. It incorporates a PA, an LNA with bypass mode, power detector, harmonic filter, 2,170-MHz notch filter, and an SP3T switch. It is configured to enable switching between Wi-Fi receive, Wi-Fi transmit, and Bluetooth RX/TX modes. ($0.82 ea/10,000 — available now.)
