Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has introduced the AWB7222 power amplifier (PA) optimized for WCDMA, HSPA and LTE small-cell base-station applications.
The AWB7222 operates in the 1805-1880MHz frequency band, delivering a combination of output power, linearity, power-added efficiency and thermal characteristics. This level of performance, combined with its integration, enables manufacturers to develop compact wireless infrastructure solutions that consume less power and provide higher throughput with greater coverage, says the firm.

"We continue to expand our small-cell power amplifier family with targeted solutions optimized for the most widely used 3G and 4G frequency bands," says Glenn Eswein, director of product marketing for Infrastructure Products. "As manufacturers develop small-cell products to help carriers address rapidly increasing wireless data consumption, Anadigics' power amplifiers stand out as critical enablers," he claims. "Our small-cell product family delivers the highest output power, linearity, and efficiency in its class, enabling compact, high-throughput devices that provide an economical path to expand broadband network coverage."
Anadigics' family of small-cell wireless infrastructure power amplifiers leverages the firm's InGaP-Plus technology and design architectures. The AWB7222 offers +27dBm of linear output power for ?-Watt small-cell applications, including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE). With linearity of -47dBc ACPR (adjacent channel power ratio) at +27dBm output power and 31dB of RF gain, the AWB7222 enables higher data rates with a greater coverage area. The power amplifier also provides 13% efficiency to minimize power consumption and offer greater flexibility in the choice of network power sources.
The complete family of small-cell power amplifiers is available in compact, low-profile 7mm x 7mm x 1.3mm surface-mount packages with integrated RF matching (optimized for output power, efficiency and linearity in a 50 Ohm system) to reduce PCB space requirements.
Pre-production samples of the AWB7222 are available now for qualified programs.
