Anadigics launches three small-cell wireless infrastructure power amplifiers

Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has launched three new power amplifiers (PAs) optimized for 3G and 4G small-cell applications, including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE). Service providers are expected to increasingly leverage small-cell equipment to improve network capacity and data speeds in densely populated areas. This is exemplified by a recent presentation at LTE World Summit 2015 by Vodafone Netherlands, which discussed planned expansion of its small-cell network and the superior customer experience that it provides.

The AWB7133, AWB7137 and AWB7238 power amplifiers operate in the 2496-2690MHz, 758-803MHz and 791-821MHz frequency band, respectively, delivering a combination of efficiency, linearity, output power and thermal characteristics enabling manufacturers to develop wireless infrastructure solutions that consume less power and provide higher throughput with greater coverage, the firm claims.

"Anadigics continues to expand its industry-leading small-cell power amplifier family to address the most popular WCDMA, LTE FDD and TD-LTE frequency bands," says Charles Armour, Anadigics' senior director of business development for Wireless Infrastructure Products.  "As wireless data consumption continues to break records, our power amplifiers enable the design of high-throughput, reliable, and compact small-cell base stations," he adds. "These solutions enable service providers to economically and pragmatically expand broadband network capacity and coverage."

Anadigics' complete family of small-cell wireless infrastructure power amplifiers leverages the firm's unique InGaP-Plus technology and innovative design architectures to deliver what is claimed to be industry-leading performance and integration. The AWB7133 and AWB7137 power amplifiers deliver better than 15% efficiency, 28dB gain, and -47dBc ACPR @ +24.5dBm of linear output power. The AWB7238 power amplifier features 13.5% efficiency, 30dB gain, and -47dBc ACPR @ +27dBm linear output power. 

The power amplifiers are available in the same compact, low-profile 7mm x 7mm x 1.3mm surface-mount package used across the entire AWB71XX and AWB72XX product lines, allowing the same PCB layout to be used for different bands and power levels. Anadigics' small-cell power amplifiers also offer integrated bias, eliminating the need for complicated external bias circuitry and reducing PCB space requirements.
