Anadigics adds 4G PA module for band 1 femtocells

At the 2009 GSMA Mobile World Congress in Barcelona, Spain, Anadigics Inc of Warren, NJ, USA has launched its new AWB7226 power amplifier (PA), a highly isolated, fully matched, multi-chip module (MCM) designed for the 2.1-2.7GHz frequency spectrum and engineered specifically for use in femtocell and customer premises equipment (CPE) that operate in UMTS band 1.

Femtocells solve the problem of weak wireless broadband signals in homes and offices by allowing mobile devices to connect to their carrier's network through a high-speed Internet link.

“The AWB7226 enables connectivity in the most popular 3G band worldwide,” says Joe Cozzarelli, Anadigics’ director, Wireless Infrastructure and 4G Products. “Its balanced design delivers exceptional linearity, high power, optimized performance and integrated functionality to simplify femtocell designs and assure reliable, high-speed connectivity,” he claims.

The femtocell market represents a new market opportunity for Anadigics’ power amplifiers, says Dr Ali Khatibzadeh, senior VP & general manager, Wireless. "The tough macro-economic conditions are putting pressure on capital expenditure by major wireless operators, making femtocells a very attractive, low-cost path to increased capacity and data ARPU [average revenue per user],” he adds. “Our technology and product differentiation position Anadigics well to gain share in this emerging market,” he reckons.

The 4.2V module operates at UMTS band 1 downlink frequencies of 2.11–2.17GHz. It has been designed to handle WCDMA, HSPA and LTE (long-term evolution) waveforms with a P1dB of 34dBm and 30dB of gain. With a WCDMA waveform, the module delivers 25.5dBm of rated power.

The AWB7226 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.

Samples will be available in March.
