World's First Penta-Band, Multi-Mode 3G (GPRS/EDGE/HSDPA) Power Amplifier

Europe Spain : ANADIGICS introduced two new multi-mode, multi-band power amplifiers (PAs). The AWT6223 offers a single-package GPRS/EDGE/WCDMA solution by combining IMT-band WCDMA operation with quad-band polar EDGE functionality.

The AWT6225 integrates an IMT-band WCDMA PA with quad-band GSM/GPRS capabilities. The new High Speed Downlink Packet Access (HSDPA) compliant multi-mode power amplifiers allow wireless handset manufacturers to satisfy the growing demand for 3G high-speed multimedia services, while saving 25% printed circuit board (PCB) space compared with typical multi-module solutions.

"ANADIGICS' new multi-mode 3G power amplifiers, which integrate GSM/GPRS and EDGE functions in the same package, offer customers a significant size reduction in terms of board space and height, enabling ultra-thin wireless product designs," said Dr. Ali Khatibzadeh, Senior Vice President and General Manager of Wireless Products at ANADIGICS.

"The best-in-class integration and performance offered by these power amplifiers help to overcome the challenges that arise from complex multi-PA RF designs and increase ANADIGICS dollar content per 3G handset." ANADIGICS' new family of multi-mode 3G PAs utilizes the Company's second-generation High-Efficiency-at-Low-Power (HELP2(TM)) technology to reduce WCDMA average power consumption by 50%.

In WCDMA mode, the power amplifier offers outstanding efficiencies of 43% at 28.5 dBm and 21% at +16 dBm, resulting in longer battery life and additional talk-time. In GSM mode, the power amplifiers provide efficiency of 55% in the GSM850/900 bands and 50% in the DCS/PCS bands.

ANADIGICS' new multi-mode PAs use the Company's exclusive InGaP-Plus(TM) technology, which integrates bipolar and field-effect transistor (FET) structures on the same InGaP GaAs die. The new penta-band power amplifiers are offered in compact 6 mm by 8 mm by 1 mm modules and include an internal voltage regulator. Both the AWT6223 and AWT6225 provide an integrated power control scheme with a 50 dB range to speed production calibration and reduce the number of external components. The products are manufactured using a materials set consistent with the European Union's Restriction of Hazardous Substances (RoHS).
The AWT6223 is priced at $5.50 in quantities of 10,000 units, and the AWT6225 is priced at $4.30 in quantities of 10,000 units. Samples are available now.
