ANADIGICS expands WiMAX amplifier portfolio to include solutions for mobile applications

(Product News, 26 Feb 2007)

ANADIGICS Inc. has expanded its portfolio of WiMAX power amplifiers (PAs) with the introduction of the AWM6423. The AWM6423 PA for mobile WiMAX supports the 802.16e-2005 standard, offering unparalleled power efficiency and high linearity in a highly integrated module package. The company already supplies prominent WiMAX equipment manufacturers with PAs such as the AWM6430, AWM6431 and AWM6432 for fixed-point 802.16d-2004 applications.

"ANADIGICS continues to innovate and offer industry-leading products by leveraging our power amplifier design expertise, advanced technology, and strong industry relationships," said Ron Michels, Senior Vice President and General Manager, Broadband Products, ANADIGICS. "Our WiMAX power amplifiers provide high linearity and advanced functional integration to support high performance solutions for the world's emerging broadband wireless systems, and superior efficiency to increase battery life for a more satisfying mobile experience."

ANADIGICS' highly integrated 4.5x4.5mm AWM6423 WiMAX PA module provides an integrated step attenuator and output power detector, minimizing external component count, PCB space requirements, and development costs for new designs. The PA operates with an exceptional power efficiency of 20% using a +3.3V supply, supporting an error vector magnitude (EVM) of 4% at +23.5dBm output power for 16-QAM signals. Excellent linearity and an EVM of 2.5% can be achieved to support 64-QAM signals by either reducing output power or increasing supply voltage. The PA module offers fully matched RF ports and can operate from a +2.9V to +4.2V power supply.

ANADIGICS' WiMAX PAs are based on ANADIGICS' patented InGaP-Plus process technology which supports enhanced feature integration and provides superior performance and reliability. ANADIGICS' WiMAX PAs are fully compatible with the IEEE 802.16 and ETSI EN301-021 standards, and are manufactured using a materials set consistent with the European Union's Restriction of Hazardous Substances (RoHS) directive.
