Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its AWB7122 and AWB7222 small-cell power amplifiers to Nextivity Inc of San Diego, CA, USA (a global provider of indoor coverage technology). Nextivity is using Anadigics’ small-cell power amplifiers in the third generation of its Cel-Fi smart signal boosters, which are authorized by 146 global carriers (including AT&T and T-Mobile) in 74 countries for use on their networks.
“Poor cellular signal strength continues to be an issue for many mobile subscribers inside their homes and businesses,” says Nextivity’s chief technology officer Michiel Lotter. “As a result, we are seeing ongoing demand for our smart signal boosters, which improve voice coverage, data throughput, and battery life,” he adds. “We chose the competitively priced, high-performance Anadigics family of amplifier products as they support the broadest range of UMTS/LTE frequency bands, offer scalable power levels within a single footprint, and enable rugged designs capable of withstanding electrical overstress conditions,” Lotter notes.
“While carriers continue to expand and strengthen their wireless infrastructure, many users still experience limited signal strength indoors,” says Tim Laverick, Anadigics’ senior VP of Infrastructure Products. “Nextivity’s newest signal boosters utilize our high-performance small-cell power amplifiers to address this challenge, delivering enhanced coverage.”
Anadigics’ complete family of small-cell wireless infrastructure power amplifiers leverages the firm’s unique InGaP-Plus technology and uniquely design architectures to deliver performance that, combined with a high level of integration, enables manufacturers to develop compact wireless infrastructure solutions that consume less power and provide higher throughput with greater coverage.
The AWB7122 small-cell power amplifier delivers 24.5dBm linear output power for -Watt applications, while the AWB7222 power amplifier offers 27dBm linear output power for -Watt applications. Both feature high linearity (supporting WCDMA, HSPA, LTE FDD and TD-LTE small-cell base-stations), enabling picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE) to achieve higher throughput (data rates) and greater coverage area, it is claimed. The AWB7122 and AWB7222 provide 16% and 13% efficiency, respectively, to minimize power consumption and offer greater flexibility in the choice of network power sources.
