HSDPA-compliant WCDMA PAs lower power consumption


Three new wideband CDMA (WCDMA) power amplifiers (PAs) offer industry-leading power efficiency to extend battery life in mobile handsets and WCDMA-enabled notebook PC cards. The high-efficiency-at-low-power (HELP) PAs offer full compliance with HSDPA (High Speed Downlink Packet Access) requirements, while maintaining compatibility with UMTS (Universal Mobile Telecommunications System) data services to support the growing demand for mobile high-speed Internet services.

Anadigics' HELP WCDMA PAs use the company's proprietary InGaP-Plus technology, which integrates bipolar and field-effect transistor (FET) structures on the same InGaP GaAs die. The PAs offer quiescent currents of 16 mA or lower, provide leakage currents of less than 1 ΜA, and are optimized for all output power levels to deliver 50% less average power consumption. The PAs are offered in a 10-pin, 4-by 4- by 1.1- mm surface-mount package designed for applications that require the European Union’s Restriction of Hazardous Substances (RoHS) solutions.

The AWT6272 operates in the U.S. Cellular 824- to 849-MHz band; the AWT6276 works in the U.S. PCS band (1850 to 1910 MHz); and the AWT6277 is for the IMT 1920- to 1980-MHz band. The three parts are priced at $2.46 in quantities of 10,000 units. For additional information, visit the company's Web site at www.anadigics.com.
