Anadigics' HELP4 PA powers Casio's G’zOne smartphone for KDDI in Japan

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its AWT6621 — which is part of its fourth-generation High-Efficiency-at-Low-Power (HELP4) power amplifier (PA) product family — to Casio for the G’zOne IS11CA smartphone.

The G’zOne IS11CA features an IPS 3.6 inch display, 8 megapixel camera, and Android 2.3 Gingerbread operating system. These features are combined with a shockproof, dustproof and waterproof design to offer KDDI subscribers a rugged smartphone option for the EV-DO Rev. B network in Japan.

“Our HELP4 power amplifiers continue to set the performance standard with the industry’s highest efficiency and lowest quiescent current, providing mobile device manufacturers with a proven solution to longer battery life,” claims Michael Canonico, Anadigics’ senior VP of worldwide sales. 

As well as delivering a high level of integration (including internal voltage regulation and a ‘daisy chainable’ directional RF coupler with 20dB directivity, all in a 3mm x 3mm footprint), the AWT6621 PA uses the firm’s InGaP-Plus technology to achieve optimal efficiency across low-range and mid-range output power levels (via three mode states) and to provide what are claimed to be the industry’s lowest quiescent currents (less than 2mA). Average current consumption is reduced by 30% compared with previous-generation PAs. The AWT6621 can hence extend battery life in handsets, smart phones, tablets, netbooks, and notebooks, Anadigics says. The HELP4 PAs also provide highly efficient operation in CDMA, WCMDA, and HSPA+ applications.
