Anadigics’ HELP4 PAs power new ZTE Android smartphones

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its AWT6621, AWT6624, AWT6625A, and AWT6628A fourth-generation High-Efficiency-at-Low-Power (HELP4) power amplifiers (PAs) to Chinese handset maker ZTE for the V889D, V788D, N788, N910 and PF200 smartphones. The V788D, N788, N910 and PF200 feature a 3.5-inch screen, 5 megapixel camera and Android 2.3 Gingerbread operating system. The V889D has a 4-inch screen and Android 4.0 Ice Cream Sandwich operating system.

The V889D is powered by the AWT6621 and AWT6628A power amplifiers and the V788D is enabled by the AWT6621. The N788 features the AWT6625A. The N910 is powered by the AWT6624. The PF200 is powered by the AWT6624.

“We look forward to working with ZTE as it continues to develop innovative smartphones for the global wireless market,” says Michael Canonico, Anadigics’ senior VP of worldwide sales. “The strength of our product portfolio, coupled with our Asia-centric strategy, demonstrates Anadigics’ commitment to both product and service excellence,” he adds. “Our world-class applications centers in China further support Anadigics’ growth initiative.”

HELP4 4G PAs use Anadigics’ exclusive InGaP-Plus technology to achieve optimal efficiency across low-range and mid-range output power levels (with three mode states) and provide low quiescent currents of less than 4mA. Anadigics also claims best-in-class linearity at maximum output power. In particular, the AWT6621, AWT6624, AWT6625A and AWT6628A power amplifiers deliver what is claimed to be industry-leading efficiency in WCMDA, HSPA and HSPA+ systems, helping to extend battery life in handsets, smart phones, tablets, netbooks, and notebooks.

HELP4 PAs allow a high level of integration in a 3mm by 3mm footprint (with internal voltage regulation and an integrated ‘daisy chainable’ directional RF coupler with 20dB directivity) and enable an average reduction in current consumption of 30% compared with previous-generation PAs.
