Anadigics expands family of small-cell wireless infrastructure PAs

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA has launched the AWB7223, expanding it portfolio of wireless infrastructure power amplifiers (PAs) optimized for small-cell base-station applications, including microcells, picocells and femtocells. 

Anadigics says that a recent report from market research firm Mobile Experts forecasts shipments of such equipment to grow from 2.6 million devices this year to more than 20 million in 2014, emphasizing the need for small-cell solutions to support the growing capacity requirements of mobile broadband networks.

“Rising demand for mobile broadband will be the catalyst for a rapid deployment of small-cell wireless infrastructure devices,” says Glenn Eswein, director of product marketing for broadband RF products. “The AWB7223 power amplifier delivers optimal performance for a new generation of microcells, picocells and femtocells that will enable high-data-rate connectivity for a larger base of subscribers,” he adds. 

“Anadigics’ new wireless infrastructure power amplifiers provide the ideal combination of output power, power-added efficiency, and linearity required to produce highly reliable, high-performance small-cell base-stations,” claims Joseph Cozzarelli, senior director of broadband RF products. 

Supplied in a compact 7mm x 7mm x 1.3mm surface-mount package, the AWB7223 provides what is claimed to be best-in-class power-added efficiency (PAE) of 15% at rated output power for WCDMA, HSPA and LTE small-cell base-stations operating in the 1930–1990MHz frequency band, with output power of +27dBm and linearity of –50dBc ACPR @ ±5MHz (WCDMA). Anadigics says that this combination of critical performance parameters extends the range of small-cell base-stations while enabling solutions that are more thermally efficient and consume less power.

Anadigics’ family of small-cell wireless infrastructure power amplifiers are manufactured using the firm’s indium gallium phosphide (InGaP) heterojunction bipolar transistor (HBT) MMIC technology.

Engineering samples of the AWB7223 are available now, as are pre-production samples of the AWB7123, AWB7127 and AWB7227.
