Anadigics expands small-cell wireless infrastructure power amplifier family for Band 8 WCDMA/LTE

Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has introduced the AWB7229 small-cell power amplifier (PA), optimized for efficiency, linearity, output power and thermal characteristics in WCDMA, HSPA, LTE FDD and TD-LTE small-cell base-stations operating at Band 8 (925-960MHz) frequencies. Manufacturers can leverage this performance to develop infrastructure solutions that consume less power, offer higher throughput, and provide greater coverage and range, says the firm.

"The rapid increase in wireless data consumption places tremendous pressure on existing wireless infrastructure," says Charles Armour, senior director of business development for Wireless Infrastructure Products. "With the industry's broadest portfolio of high-performance power amplifiers for small-cell applications, Anadigics is enabling the newest generation of high throughput, reliable, and compact base stations, including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE). These solutions provide an economical and pragmatic path to expand broadband network capacity and are gaining momentum with service providers."

Anadigics' family of small-cell wireless infrastructure power amplifiers leverages the firm's InGaP-Plus technology and design architectures. The AWB7229 delivers 13% efficiency to minimize power requirements. With linearity of -47dBc ACPR (adjacent channel power ratio) @ +27dBm linear output power and 29dB gain for ½-Watt linear output power applications, it is optimized to provide high-throughput data rates with a wide coverage area.

The AWB7229 power amplifier is 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. The AWB7229 also offers an integrated +4.5V bias, eliminating the need for complicated external bias circuitry, which simplies design and system integration and reduces PCB space requirements.
