Anadigics adds small-cell wireless infrastructure PAs for E-UTRA Band 7 WCDMA/LTE

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA has expanded its family of small-cell infrastructure power amplifiers (PAs) to support E-UTRA Band 7 WCDMA and LTE applications by launching the AWB7128 and AWB7228 PAs.

Anadigics says that its family of small-cell infrastructure PAs delivers a combination of high output power, efficiency, and linearity, optimized for the rapidly growing class of small-cell base stations that includes picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE).

“The continual increase in consumer demand for wireless data is fueling the rapid deployment of small-cell wireless infrastructure devices, such as picocells and femtocells,” says Glenn Eswein, director of product marketing for broadband RF products. “Anadigics’ small-cell power amplifier family delivers the highest output power, power-added efficiency, and linearity in its class, enabling manufacturers to develop compact, esthetic, high-throughput devices that offer service providers an economical path to expand broadband network coverage,” he claims. “Working closely with device manufacturers, we are expanding this family to help bring the same performance and design flexibility to additional frequency bands.”

The AWB7128 and AWB7228 are optimized for WCDMA, HSPA, and LTE small-cell base-stations operating in the 2620-2690MHz frequency band. The AWB7128 provides +24.5dBm linear output power (optimized for ¼W applications), while the AWB7228 delivers +27dBm linear output power (optimized for ½W applications). The PAs use Anadigics’ exclusive InGaP-Plus technology to achieve what is claimed to be best-in-class power-added efficiency (PAE = 15% for the AWB7128 and 14% for the AWB7228) and linearity (-47dBc ACPR @ +/- 10MHz offset; 10MHz channel bandwidth) at these output power levels, enabling small-cell wireless infrastructure solutions that are more thermally efficient, consume less power, and provide greater range.
In a compact 7mm x 7mm x 1.3mm surface-mount package, integration includes RF matching optimized for output power, efficiency, and linearity in a 50 ohm system

Engineering samples of the AWB7128 and AWB7228 are available now for qualified programs.
