Anadigics introduces InGaP Multimode Multiband PAs
These compact and efficient indium gallium phosphide MMPAs are suited to Quad-Band GSM/ EDGE and dual-band WCDMA/LTE applications
Anadigics says its new PAs reduce RF space requirements in handsets, smart phones, tablets, netbooks, and notebooks.
Anadigics’ MMPA 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 characterised by high efficiencies at all power levels, while the EDGE performance meets all stringent modulation mask requirements under all conditions.
Engineering samples of the ALT6181 are available now.
Cellular PA market to reach $4 billion in 2016 with the help of GaAs
“Mobile devices continue to evolve in both form and function, creating performance and size constraint challenges on the RF front-end,” said John van Saders, senior vice president of RF products at Anadigics.
“Anadigics has responded to these challenges by continuously improving power amplifier performance and integration. The introduction of our new multimode multiband power amplifiers extends our high performance RF integration. By delivering a converged solution with industry-leading performance, we are able to provide manufacturers with greater design flexibility to enable the next- generation of mobile devices.”
Anadigics multimode multiband power amplifiers are optimised 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 market for gallium arsenide-based PAs will continue to grow in more demanding applications and more sophisticated smartphones
The cellular power amplifier (PA) market grew 19 percent, to more than $3.3 billion in 2011, driven by the growth of cellular terminal shipments to an estimated 2.3 billion units.
The Excel-based report, “Cellular PA Forecast 2012,” from the Strategy Analytics RF & Wireless Components (RFWC) service covers the market for PAs and PA-front-end modules in dollars and units through 2016.
According to Christopher Taylor, Director, Strategy Analytics RF & Wireless Components, “Grey market (illegal, or shanzhai) handsets grew, as did smartphones, cellular-enabled notebooks, netbooks, tablets, USB dongles and M2M devices. The average number of bands and modes supported by cellular devices also grew, which slightly increased the average number of PAs per cellular device 2011. Strategy Analytics expects the non-handset segments of this market to contribute
