Anadigics’ HELP4 and HELP3E PAs power Samsung Galaxy Note in China and Korea

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its ALT6705, AWT6621 and AWT6624 fourth-generation High-Efficiency-at-Low-Power (HELP4) power amplifiers (PAs) and AWC6323 dual-band third-generation High-Efficiency-at-Lower-Power (HELP3E) power amplifiers (PAs) to Samsung Electronics for its Galaxy Note devices. The AWT6621 powers the Galaxy Note I9228 (TD-SCDMA) and the AWC6323 powers the Galaxy Note I889 (CDMA), both available in the China market. The ALT6705, AWT6621, and AWT6624 power the Galaxy Note SHV-E160L, available in Korea.

The Samsung Galaxy Note features a 5.3-inch high-definition super AMOLED screen and is capable of displaying movies at full1080p. Also, the slim Galaxy Note has an 8 megapixel camera, 1.4GHz dual-core processor, and Android 2.3 Gingerbread operating system.

“The new Samsung Galaxy Note represents an advanced convergence device that merges the impressive multimedia features of a tablet with the versatility and functionality of a smartphone,” comments Michael Canonico, Anadigics’ senior VP of worldwide sales. Anadigics’ power amplifiers help to extend battery-life in power hungry multimedia-rich devices, he adds.

Anadigics’ HELP4 and HELP3E PAs use the firm’s exclusive InGaP-Plus technology to achieve optimal power-added efficiency (PAE) across low-range and mid-range output power levels (with three mode states) and provide low quiescent currents of 4mA. Anadigics also claims best-in-class linearity at maximum output power.  

Devices in the HELP3E family incorporate two independent PAs in a single package with a 3 mm by 5 mm footprint, along with internal voltage regulation and an integrated RF coupler.

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.

In particular, the ALT6705, AWT6621, AWT6624 and AWC6323 power amplifiers deliver what is claimed to be industry-leading efficiency to extend battery life in handsets, smart phones, tablets, netbooks, and notebooks.
