Fairchild Semiconductor’s 4x4mm Dual-Band Power Amplifier Saves Space, Extends Range in WLAN Applications

  South Portland, Maine– Building upon its industry-leading portfolio of WLAN power amplifiers (PA), Fairchild Semiconductor (NYSE: FCS) introduces the FMPA2151, a highly integrated dual-band WLAN power amplifier module optimized to increase performance and reduce PCB board footprint in the latest 802.11a/bg WLAN applications, including notebooks, digital cameras and portable handsets.

The high-performance FMPA2151 offers leading-edge 3.5 percent error vector measurement (EVM) at 20dBm output power, which helps to extend the wireless range in computing applications for worldwide Internet connectivity. The dual-band FMPA2151 saves designers up to 22 percent board space by combining 2.4GHz 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. These application and design benefits aid designers by easing design complexity and accelerating time to market.

“WLAN computing designs increasingly demand more compact form factors and fewer peripheral components. 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,” said Russ Wagner, general manager of Fairchild’s RF Power Products Group. “Our dual-band amplifier also facilitates easy WiFi® hookups over an extended range worldwide by allowing WLAN-enabled terminals to locate the best available frequency band. This is an important feature in the latest wireless notebooks offering worldwide Internet connectivity.”

The FMPA2151 expands Fairchild’s world-class portfolio of linear PA modules offering more functionally integrated devices for computing applications, including the RMPA5255, another high-performance device for 4.9-5.9GHz WLAN applications, and the RMPA2458, a 2.4-2.5GHz linear power amplifier.

This power amplifier exemplifies Fairchild’s ability to apply its design expertise to integrate the most advanced functionality into one package. In addition to the FMPA2151, Fairchild offers a broad range of solutions for computing applications. These include multi-phase DC/DC controllers, such as VRMx/VRDx solutions; buck regulator high- and low-side application-specific MOSFETs; and multiple point-of-load devices, including LDOs and integrated switches that offer up to 95 percent efficiency.

Fairchild’s FMPA2151 is available in a 4x4, 16-terminal lead (Pb)-free package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C and is compliant with the European Union requirements now in effect.
