Anadigics Inc. unveiled three new W-CDMA power amplifiers (PAs) that promise industry-leading power efficiency to extend battery life in mobile handsets and W-CDMA-enabled notebook PC cards.

The new 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.

"The migration of 3G W-CDMA technology to the HSDPA standard enables a new class of wideband services for consumers while simultaneously raising the bar on the power consumption requirements of mobile products," said Dr. Ali Khatibzadeh, Senior Vice President and GM of wireless products at Anadigics. "These HSDPA complaint W-CDMA PAs utilize our innovative HELP technology to offer best-in-class power consumption for mobile 3G products."

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

The AWT6272 (824MHz to 849MHz frequency band), AWT6276 (1,850MHz to 1,910MHz) and AWT6277 (1,920MHz to 1,980MHz) are priced at $2.46 in quantities of 10,000 units. Samples are already available.
