Anadigics expands family of small-cell wireless infrastructure PAs for Band 5 WCDMA and LTE applications

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA has launched the AWB7125 and AWB7225 small-cell power amplifiers (PAs), optimized for Band 5 WCDMA and LTE applications including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE).

“The rapid growth in mobile data usage is driving carriers to seek cost-effective methods to increase network capacity, especially in dense geographic locations,” says Glenn Eswein, director of product marketing for broadband RF products. “Small-cell devices, such as picocells and femtocells, provide carriers with an economical, high-performance solution that can be deployed quickly,” he adds. Anadigics’ small-cell power amplifiers have been developed specifically for these applications, and enable wireless infrastructure solutions that are more thermally-efficient, consume less power, enable higher throughput, and provide greater coverage and range, it is claimed.

Performance is optimized for linear output power of 1/4 Watt, +24.5dBm (AWB7125) and 1/2 Watt, +27dBm (AWB7225). RF matching is optimized for output power, efficiency and linearity in a 50 ohm system, and housed in a compact 7mm x 7mm x 1.3mm surface-mount package. Both power amplifiers are compliant with WCDMA, HSPA, and LTE small-cell base-stations operating in the 860-894MHz frequency band.

Anadigics’ complete family of small-cell wireless infrastructure power amplifiers is manufactured using the firm’s exclusive InGaP-Plus technology to achieve what is claimed to be best-in-class power-added efficiency (PAE) of 15% (AWB7125) and 13% (AWB7225) at rated output power, exceptional linearity of -47dBc ACPR @ +/- 10MHz offset (10MHz LTE channel bandwidth), and excellent thermal performance (with low transistor junction temperature).

Pre-production samples of the AWB7125 are available now. Engineering samples of the AWB7225 are available now for qualified programs.

Anadigics is exhibiting in booth 3514 at the 2012 IEEE MTT-S International Microwave Symposium (IMS) in Montréal, Canada (19-21 June). Also, on 20 June at 3pm in the Richardson RFPD booth (number 1818), Eswein will give a presentation focusing on small-cell wireless infrastructure power amplifiers.
