Anadigics launches its first power amplifier for femtocells

GaAs-based broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has launched the AWB7220 power amplifier (PA), the first in its new line of products targeted at the 3G and 4G femtocell markets.

The AWB7220 PA is a highly isolated, fully matched, multi-chip module (MCM) designed and engineered specifically for use in femtocell and customer premises equipment (CPE) worldwide.

Femtocells solve the problem of weak or non-existent wireless broadband signals in SOHO environments by connecting users’ mobile devices to their carrier’s network through a high-speed Internet link. Because they are inexpensive and easy to install and operate, sales of femtocells are expected to ramp up significantly in 2009. Analyst firm ABI Research sees the femtocell market increasing to double-digit millions in volume during 2010. “We expect cellular-based femtocells to take the baton from UMA- and SiP-based Wi-Fi solutions by 2013, seizing 62% of the 103 million unit access point market,” says ABI VP & research director Stuart Carlaw. ABI also expects femtocell prices to drop to the range of wireless routers in 2010.

“The femtocell market is an exciting place to be right now... It’s a milestone in the convergence between consumer electronics and commercial network infrastructure,” comments Joe Cozzarelli, Anadigics’ director for Wireless Infrastructure and 4G Products. “We’re leveraging Anadigics' proven, core GaAs technology and our engineering expertise to design and manufacture a comprehensive product line with the exceptional linearity, high power, optimized performance and integrated functionality required by femtocell equipment designers and manufacturers,” he claims.

The AWB7220 is a 4.5V module that operates at 2.5-2.7GHz with extended operational capability between 2.3GHz and 2.5GHz. Designed specifically for OFDMA waveforms such as 802.16 WiMAX, the new module delivers 28dBm (P1dB = 35dBm) output power with 30dB of gain.

The AWB7220 is manufactured using Anadigics’ proprietary InGaP-Plus technology. Its self-contained 7mm x 7mm x 1mm surface-mount package incorporates matching networks optimized for output power, efficiency and linearity in a 50Ω system.
