ANADIGICS, Inc. (Nasdaq: ANAD) has introduced a new multimode multiband power amplifier (MMPA). The ALT6181 MMPA utilizes ANADIGICS’ third generation High-Efficiency-at-Low-Power (HELP3E™) technology to provide high efficiency in a single module solution for quad-band GSM/EDGE and dual-band WCDMA/LTE mobile applications. This world-class combination of performance and integration helps extend battery life and reduce RF space requirements in handsets, smart phones, tablets, netbooks, and notebooks.

ANADIGICS MMPAs are optimized to deliver compelling performance under LTE, WCDMA and CDMA signal modulations for bands 1, 5, 6, 18, 19, and 26. Efficiency, current consumption, and linearity specifications have been enhanced for all modulations while ensuring that critical harmonic, noise, and intermodulation performance results in superior phone level performance. The solution uses the company’s exclusive InGaP-Plus™ technology and HELP architecture to achieve optimal efficiency across low-range and mid-range output power levels, without the use of a DC-DC converter. When paired with a DC-DC convertor, the MMPA can deliver additional performance benefits.

The compact 5 mm by 7.5 mm MMPA features an integrated voltage regulator and separate single-ended RF chains. The inclusion of high directivity couplers also ensures optimum system performance. The GSM performance of the MMPA is characterized by high efficiencies at all power levels, while the EDGE performance meets all stringent modulation mask requirements under all conditions.
