WLAN/Bluetooth-modul til indbygning

SiGe Semiconductor lancerer kombineret front-end WLAN/Bluetooth modul til indbygning i mange typer af applikationer (in english).

SiGe Semiconductor has expanded its Wi-Fi product range by introducing the SE2571U front end module that is specifically targeted at embedded applications including cellular handsets, gaming, digital cameras and Personal Media Players (PMP).  

The SE2571U has been designed to address the specific challenges faced by OEMs needing to operate 'direct to battery', and to improve performance, while addressing consumer led demand for coexistence with UMTS radios.

The SE2571U provides a complete 2.4 GHz WLAN RF transmit and Bluetooth receive solution from the output of the transceiver to the antennas and from the antennas to the input of the transceiver.


It incorporates a high performance power amplifier,  low noise amplifier with bypass mode, power detector, harmonic filter, 2170 MHz notch filter, an SP3T switch and is configured to enable switching between Wi-Fi receive, Wi-Fi transmit and Bluetooth RX/TX.   It delivers 20dBm in 802.11b mode and a full 19dBm linear power in 802.11g mode; it can operate from 2.7 to 4.8V for direct to battery applications, thus removing the need for any supply regulation. 

The integrated filtering ensures compliance with unwanted spurious emissions in the transmit path and provisions for co-existence operation when a cellular signal is present in the receive path.

- We are very pleased to launch the SE2571U Front end module to address
these rapidly growing embedded Wi-Fi markets, says Sanjiv Shah, director, product marketing WiMAX, & embedded WLAN at SiGe.
- This new FEM delivers the reliability, flexibility, and performance OEMs require and consumers demand. It significantly reduces device bill of materials and board assembly costs as well as the overall system footprint, all of which are paramount in embedded applications.

The SE2571U comes in a small lead and halogen free, ROHS compliant 3 mm x 3 mm x 0.5 mm, MSL 1, package, this low profile package height makes it suitable for integration in WLAN modules.  

The SE2571U is priced at US$0.82 in 10k quantities it is sampling now and is offered with applications documentation and evaluation boards.
