Power player for WLAN apps

Notebooks, digital cameras, and portable handsets—some of the latest 802.11a/b/g WLAN applications—can now take advantage of the FMPA2151 power-amplifier (PA) module. Developed by Fairchild Semiconductor, the highly integrated dual-band WLAN module is designed to increase performance and reduce PCB board footprint.

The FMPA2151 offers 3.5% error vector measurement (EVM) at 20dBm output power, which helps to extend the wireless range in computing applications for worldwide Internet connectivity. It saves designers up to 22% board space by combining 2.4 and 5GHz power amplifiers into a single compact 4x4mm package.

For additional space savings, as well as enhanced reliability, the device provides built-in power detectors and digital PA on/off controls. As a result, it eases design complexity and accelerates time to market.

"WLAN computing designs increasingly demand more compact form factors and fewer peripheral components," says Russ Wagner, general manager of Fairchild's RF Power Products Group. "The FMPA2151 module answers these requirements by replacing two power amplifiers typically used in WLAN designs with one integrated dual-band device, therefore reducing component count and saving board space.

"Our dual-band amplifier also facilitates easy WiFi hook-ups over an extended range world-wide by allowing WLAN-enabled terminals to locate the best available frequency band."

Fairchild's FMPA2151 comes in a 4 x 4, 16-terminal lead (Pb)-free package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C, and complies with the European Union requirements now in effect.
