Anadigics’ New HELP3DC™ Power Amplifiers Bring the Performance of HELP™ Technology to Cellular Devices That Utilize SMPS, DC/DC Converters, and Envelope Tracking
Anadigics, Inc. has introduced a new series of power amplifiers (PAs), leveraging the Company’s third generation High-Efficiency-at-Low-Power (HELP™)technology. The new HELP3DC™ AWT663x series PAsare optimized for CDMA, WCDMA/HSPA, and LTE devices that include a switched-mode power supply (SMPS), DC/DC converter, or Envelope Tracking IC to control the PA supply voltage. In this kind of design, HELP3DC™ PAs provide the world-class average current consumption to help extend battery life in handsets, smart phones, tablets, netbooks, and notebooks.

“ANADIGICS continues to raise the bar for wireless power amplifier performance with the introduction of our new HELP3DC™ series, optimized for devices that include DC/DC converters in their RF power management strategy,” said Bruce Webber, director of marketing for wireless RF products at ANADIGICS. “This addition to our successful and industry-leading HELP™ product family provides RF designers with more options to achieve longer battery life, enabling mobile device users to experience the full potential of mobile broadband 3G and 4G services.”

SMPS and DC/DC converters allow handset designers to reduce the PA supply voltage, decreasing average current consumption under selected conditions. ANADIGICS’ HELP3DC™ PAs have two power modes for high efficiency across both low and high RF power levels from a fixed supply. These PAs also provide exceptionally low quiescent currents. Using a HELP3DC™ series PA in combination with an external DC/DC converter gives designers additional options to reduce battery current consumption in both high power and low power modes. Envelope tracking designs modulate the PA supply voltage to match the demands of the input RF signal. In Envelope Tracking designs, HELP3DC™ PAs can provide world-class performance and efficiency.
