Anadigics’ MMPA powers Samsung Galaxy S Relay 4G smartphone

GaAs-based broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its ALT6181 multimode multiband power amplifier (MMPA) to Samsung Electronics for the new Galaxy S Relay 4G. The new smartphone provides a 4-inch super AMOLED touchscreen display (as well as a slide-out QWERTY keyboard, 1.5GHz dual-core processor, and Android 4.0 Ice Cream Sandwich operating system.

Anadigics says that the MMPAs leverage its InGaP-Plus technology and patented design architectures to provide a single-package solution for quad-band GSM/EDGE and dual-band WCDMA/LTE applications. The firm adds that its MMPAs combine integration and efficiency, helping to extend battery-life in applications where minimizing printed circuit board (PCB) space is desired, such as handsets, smartphones, tablets, netbooks, and notebooks.

“The selection of our multimode multiband power amplifier for several upcoming smartphones, including the new Galaxy S Relay 4G, exemplifies the integration and performance advantages offered by this solution,” says Michael Canonico, senior VP of worldwide sales. “By leveraging our innovative technologies, design techniques, and intellectual property, we are able to help manufacturers reduce RF PCB space requirements and extend battery-life in sleek, power-hungry mobile devices,” he adds.

The compact, low-profile 5mm by 7.5mm by 0.9mm ALT6181 MMPA has an integrated voltage regulator, separate single-ended RF chains, and high directivity RF couplers. WCDMA/LTE linearity specifications for bands 1, 5, 6, 18, 19, and 26 have been enhanced, while ensuring that critical harmonic, noise and intermodulation performance results in superior mobile device performance, it is claimed.

Anadigics says that, similar to its new ProEficient family of products, the ALT6181 MMPA provides optimal WCDMA/LTE efficiency across all power levels (>40% in high-power mode and >20% in low-power mode), without the use of a DC-DC converter. It also claims best-in-class linearity at maximum output power, and a low quiescent current of 4mA.

The firm adds that the MMPA delivers high GSM/EDGE efficiency at all power levels and meets stringent modulation mask requirements under all conditions, while EDGE mode is optimized for the best combination of linearity and efficiency.
